• The non-linear curve fit lev mar problem

  Hi, I have a set of 10000 readings recorded every second. My goal to draw these vs time readings (1-10000 s) in logarithmic scale and adjust the exponential curve that results with my model equation: a1 * exp (t * b1) + a2 * exp (t * b2) + a3 * exp (t * b3) + a4 * exp (t * b4) and get the values of the coefficients (a1 to a4, b1 - b4). I changed the non-linear adjustment of lev - mar.vi according to my model. However, I ran into a problem.  I get the following: error-20041 occurred at LM.vi:5 to get on the curve of the NI_Gmath.lvlib:Nonlinear Possible reason (s): the system of equations can be solved because the input matrix is singular. I can't work on why I get this error. I enclose 3 files: the data file (values of Y), X = 1-10000; coating not get my model and vi vi.

  I'm using Labview 8

  I would appreciate your help and suggestions! Thank you very much in advance. ANU

  Hello

  @Jim-thank you very much... ur modified vi helped a lot... but a strange thing on the adjustment is that it depends a lot on the estimation of the coefficients... my model should have values of 'a' coeffs in the order of 10 ^-7 and 'b' should be higher around 10 ^-1. The initial proposal is amended the best coefficients made vary accordingly.

  I don't really know if this can b fixed... I enclose my vi.

  VI: - non - linear adjustment model, exponential branch.

• Problem of Nonlinear Curve fit: Lev - Mar

  Hello, I am trying to use lev - mar to fit my data. I think that lev - mar is suitable for my non-linear data of the diode I - V curve. How to connect the input of the VI of lev - mar? What should I put in the data / initial settings / covariance? I've seen examples in the labview, but still can't find the solution.

  Suggest you start here: Introduction to the adjustment of the curve http://www.ni.com/white-paper/7669/en/

• Non-linear function Lev - Mar - output gradient functions reference table?

  Hello

  I have the whole 8.6 developer and am relatively new to labview.  First time posting, but these tips already have a lot of my problems solved.  Thank you!  My luck ran out however...

  I had worked on a recursive function to fit a set of nonlinear data, when I stumbled upon the function of lev - mar.  What a great discovery... it works very well.  However, I tried to determine the criteria for the named 'f '(X,a)' reference to the static VI which contains the lev - Mar function to fit the output.  The function performs fine without her that it will calculate the slopes in itself if the gradient table is empty, but it takes a little more time and I'm trying to speed up a bit.

  The example 'Fit Gauss surface with offset.vi' is the only example I could find where the output of f'(X,a) of the reference to the function VI is populated, but I'm a little rusty with my calculations and has failed to reverse engineer exactly what should be the values that they had classes in this table.

  I would like to be able to complete the table of f'(X,a) with the data of a 2d versus 3d surface curve in the example 'Fit Gauss surface with offset.vi.  Is attached a screenshot of the example showing the output in the example of f. '(X,a).

  Thank you very much!

  If you do not provide the analytical partial derivatives, LabVIEW will use automatically digital derived partial. You can watch the labview code in detail to see how it does, just open the VI and search for "LM digital gradient.vi.

  I don't know what, "recursive function" in this context, but they have an analytic expression for the partial derivatives?

  Even if the analysis of the partial derivatives are not possible, it may be an advantage to making your own derived partial inside the model. It seems to be much faster.

  You'd basically is to calculate the function several times, each time with one of the parameters that is incremented by a small delta and subtract function calculated with the current settings Plains each and divide the result by the delta. Do everything in a table 2D for the output of f'(X,a).

  The image shows one way to do this inside the model. The black square is a model where you replace you own function (f(x,a)).

• Problems of blackBerry Smartphones with error message on the Desktop Manager

  Hello

  I am having trouble with an error message that I get when I try to sync my Curve 8530 with MS Outlook 2010.  It was working fine and now I get the error message "error code-0x80043ade. See the documentation "all advice?

  Thank you!

  I had the same problem when I first tried to synchronize. The problem for me was when the BlackBerry Desktop Software has updated to Version 6, it left the old version - Version 5 - on my computer. If you go into the Control Panel on your computer and uninstall the Version 5 and try to re-synchronization, it should work!

  I hope this helps!

• Fitting with integral functions

  Hello

  I try to fit the data with full functions.  It is impossible to obtain analytical solutions of the integrations.

  Integration is integral [(T - abs [x]) f (x) dx, T, - T]

  Here, f (x) is one of the functions of autocorrelation for different model systems.

  Thank you

  Doogie

  Hi Doogie,

  We certainly have the integration and curve build VIs in LabVIEW. For example, you can find several kinds of system integrators in the mathematics > integration & differentiation palette. Also, if you use our design Simulation tools by & control, that built the integration as well. However, because you are dealing with an equation as opposed to sampled signals, I'd start by programming your equation in LabVIEW. Take a look at this forum thread that discusses this, and examples of code.

  Once you have programmed the equation and can generate an array of points for your stove, you might try to enter a function of integration as the "Integrate x (t) .vi" and then use a function as the "general polynomial Fit.vi" curve to generate an equation fitting for him. I would try getting started in this way. Please let me know if I address not the functionality that you are interested in.

• Problem to adjust the data using the algorithm of lev - mar...

  Hello

  I'm a casual user of LV, and I need signal level using a non-linear custom model. The signal is basically a decay of exp (order 1) with a continuous component, so it's pretty simple.

  When I apply the routine of Lev - Mar's non-linear editing, I've always had the famous "an exception has occurred in externally called by a function of the call library node. This could have corrupted memory of LabView. Save any work., etc.. VIwas stopped to node "" a call to "NI_AALPro.lvlib: Real - Decomposition.vi of SWINE vesicular disease.

  The thing is I've already adapted successfully some basic (linear model) data using this form of Lev - Mar non-linear... but it won't work this time... and I don't see why.

  Could you watch my VI and model definition and tell me what I need to improve, and what might cause the problem? The main VI (TPV_Fit_ExpDec1_v1.0.vi) open a text file that contains my data (3 columns: time, a pulse (not useful for editing), the signal to fit). At the beginning, I isolate the part of the signal that matches t > = 0, because it is where begins the exponential decay. So I want just to get the part. I join the main VI, a txt file containing typical data, and made the VI that define the model to the lev-mark function.

  I would appreciate your help and suggestions!

  Thank you very much in advance.

  Here's a quick rewrite. You should ALWAYS figure the curve for the initial parameter estimates see if they are in the ballpark. Rather than modify the data, you could just put the weight to zero for negatvie x. see if it works better.

  

• Kalonline-works until I get the anti-piracy icon so stop saying: there is a problem with the function of anti-hacking

  I play kalonline (RPG game), when to start the game it works up until I get the anti-piracy icon so stop saying: there is a problem with the function of anti-hacking. the program stops. I am the admin of it say kal computer run it in administrator mode and I did and I delete and reinstall the game. Solve the problem in win 7 by a right click and run as administrator, they wanted to work in win xp it all fits on how to solve this problem. These are the things, I was told to do to fix it.
  Hello

  It comes to KalOnline.

  Your error message can be corrected by following these steps:

  1. run KalOnline in Administrator Mode.

  2 uninstall KalOnline d_lete the entire Inixsoft folder, then reinstall the game.
  I did it and and it has not worked. then I was told that this was causing the problem

  Please check your computer system.

  This problem has occurred by a kind of problem of piracy.

  And if you have used a kind of memory-editing program, it could be happen too.

  So if your receipt similar to, then please remove it.
  I have none of these things on my computer. All I know is that people who have not updated windows xp can play the game and people who win 7 can play the game if they right click icon and run as administrator, that I still say side here but no way to prove it.

  Hello

  I suggest you to get in touch with the manufacturer of games and see if there are any other fix for this problem.

• Problem with SaveAs function using random paths.

  The installation program:

  Part 1) I have a script to the folder level that allows me to exercise a SaveAs function within forms. I'm doing this as a way to save the document quietly in the background. The effect is that the file is replaced with a copy of itself. The script is:

  var mySaveAs = app.trustedFunction (function (oDoc, cPath, cFlName)

  {

  app.beginPriv ();

  cPath = cPath.replace(/([^\/])$ /, ' $1 / ');

  try {}

  oDoc.saveAs (cPath + cFlName);

  } catch (e) {}

  App.Alert ("error during save it");

  }

  app.endPriv ();

  });

  Part 2) of my documents, I have to check by calling the function below:

  function runSave()

  {if (typeof (mySaveAs) == 'function') {}

  var pathArray = this.path.split("/"); "

  var myFileName = pathArray [pathArray.length - 1];

  cPath var = this.path.slice(0,myFileName);

  mySaveAs (this, cPath, myFileName);

  } else {}

  App.Alert ("Missing Save Function\n" + "Please contact forms administrator");

  }

  }

  Part 3) I have several large forms that use automatic recording to call save work according to a time interval of 5 minutes, using:

  app.setInterval (runSave (), 300000);

  The problem:

  Part 1) automatic backup function works very well and it works silently in the background. However, I started having problems when I open two forms at the same time. If, for example, I have a form of an open folder and open a form from a second folder, the save feature will sometimes save the active document in its original folder (as expected, crashing and creating an automatic registration) or sometimes save to original folder of the second document. This leaves me a copy update (automatic check) of the document in the right folder, and a copy not updated in the original folder. This seems to vary on what document I opened finally or document that is currently active. Although I can't find the right combination.

  It's like thinking what is to confuse the "this.path.

  Part 2) worse, if two documents have the same name, as is often the case with these forms, any incorrect saving deposit causes a crash of the second document and data loss.

  Part 3) makes it maddening, as sometimes happens when no record or the second second document is open. Instead, damaging it saves the active document in a recently viewed folder. For example, I'm going to open a local folder and open a Word doc, close the file and the doc, go to another folder in a different root (a folder in network), open the form and automatically saves it on the local computer in the folder with the Word doc. So now not only do I have a copy not updated in my folder, I have no idea where the updated copy was actually saved to until I met some time later.

  Part 4) once again, worse still, the previously viewed folder could happen which contains a document with the same name, and that the document is crushed by the automatic backup. I have no idea that the form was crushed until I sometimes open a little later and see that it contains a completely different form data.

  What is happening and how it stop?

  Adobe Acrobat X Pro on a PC.

  The code for this tutorial is unfortunately wasn't working, I discovered recently.

  This is my own personal code for a trust saveAs method. Note that it takes 2 parameters, not 3.

  safeSaveAs = {app.trustPropagatorFunction (function (doc, vPath)}

  app.beginPriv ();

  doc.saveAs({cPath:vPath});)

  app.endPriv ();

  });

  myTrustedSaveAs = {app.trustedFunction (function (doc, vPath)}

  app.beginPriv ();

  safeSaveAs (doc, vPath);

  app.endPriv ();

  });

  You call it like this:

  myTrustedSaveAs (this, "/ c/temp/test.pdf");

• Error with the function "Open/create/overwrite file" with cancel button

  I have attached a very simple VI who embodies what I want to do with my function to open the file. I just want to stop the rest of my program (theoretically embedded in the Structure box) to run if the user deigns to do not to specify a file location.

  However, if you click on the button cancel an error is produced before the rest of the program is running. If ignore you the error and continue, the "canceled" properly true made variable and the Structure of business runs correctly. "" I just want to remove the error message given to me by LabVIEW.

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
