Curve fitting only part of a waveform

• Introduction to the tutorial of curve fitting - curve example of non-linear editing

  As stated in my first question, I asked yesterday I'm new to labview and I always work in the curve editing tutorial, but I am now up to the non-linear section (although I jumped the polynomial stuff for now).  So my question now to do the with the vi illustrated in Figure 14 of the Introduction to the tutorial Curve Fitting.

  My problem this time has do with graphic design for data non-linear Gaussian and adapt.  Looks like it gets its data from a cluster of some sort which is itself drawn to clusters separate construction.  The problem is that I can't find the appropriate function of cluster, which will result in the production of a graph.  I had a test using a variety of different cluster functions and also have a look to try to use a matrix function and none of them work.  Now, an assumption that I did is also that the graph is of the form XY (and not a waveform graph).

  Note that I am aware that part of the problem could be my lack of experience in coding using labview, as I've attached the vi that I worked on.

  I'm using labview 8.6.

  Thanks again for any help.

  Do not use the function you are using.  Use the cluster on each plort bundle, then build the table of these 2 groups.

  To the Subvi, you right-click the entry that caused the broken arrow and choose create constant.

  Whenever you have a problem trying to find the right data type into a Subvi.  Do a right click, create constant.  Now, you will have a default constant of the correct data type that you can modify as needed.

  

• Fit Gaussian Peak and non-linear curve Fit on small data differ from the PEAK of origin made

  Hi all

  I'm developing a program in which I have to adjust the curve of Gauss on only 4 or 5 data points. When I use the Gaussian Ridge Fit or adjustment of the curve non-linear, it connects linearly all the points so that other editing software like origin's curve fitting of Gauss on the same set of data that I have attached two images is LabVIEW with Fit Gaussian of Peak and nonlinear adjustment and other is original.

  The data are

  X                       Y

  799.09857 257
  912.25256 641

  1026.00366 1516
  1137.92871 1118
  1253.43713 329

  Interesting.

  The initial default values assume all are NaN, which causes the LV calculate conjecture.  The default values for the parameter Bounds +/-Inf with the exception of the offset that are both zero. This, of course, forces the output zero offset.  It seems a strange fault, but they may have a good reason for it.

  Change the limits of compensation to something else translates the output being offset ~ 215 and the Center moves to ~ 1053.  These correspond the original result to 5 significant digits.

• OfficeJet Officejet Pro 8500 has more eAiO Scan to computer scans only part of the Document

  I am trying to scan my Officejet Officejet Pro 8500 has more eAiO scan to my iMac (Mac OS X 10.6.8).) IT scans only part of the document is scanned. However, when I copy it, the entire document is printed. I was looking for, if I could change this on the officet, or the system of preferences on my mac, but couldn't find anything on the 8500. On mac, I could change something, but it was only the scans on insiders from my computer.

  Scanning directly from the Officejet comes in very handy when the digitization of books, with one hand, I have to push it and the iMac is not in reach of the officejet...

  Otherwise, I am very satisfied with the printer and everything works fine...

  Thanks for any help.

• Introduction to the tutorial of curve fitting - find a function

  I'm new to programming in Labview (and programming in general) and so I'm learning the different functions in Labview that are likely to be relevant to the work that I do.  One of the functions I'll take advantage in Labview is the curve of the functions.  To this end, I found a number of tutorials that are available in the area of the developer, and the plan is to work my way through some tutorials apply in order to understand the processes involved (and how to use features etc.).

  The tutorial that I am currently working my way through is the Introduction to the tutorial Curve Fitting, and is where I am currently blocked.  To work through the linear curve of squares vi, as shown in Figure 3 of the tutorial, I can't seem to find the function that the linear data vi and the vi curve are interconnected and which connects to the curve of the linear model.  When I say that I can't find the function I want to say that I can't find the feature with the Schwaar icon in the Labview version that I use currently (it is the Labview 8.6 development system).  Can I get help with the function I need to use?

  I note, however, that the tutorial was written in 2006.  Would be - why I'm unable to find the function indicated (that is to say, he has changed since this tutorial was written)? If this is the reason why, anyone knows what is now the correct function?

  The tutorial can be found here: http://zone.ni.com/devzone/cda/tut/p/id/7669.

  Thanks for your help.

  Hey Scottum,

  This is the function table to build in the range of table in respect of the programming.

  If you hover over it in top and bottom of the function, you should see two small squares.  Mouse over the squares and your mouse turns into a vertical head double arrow.  You can drag the mouse in the vertical direction to expand the service to include more inputs.

  Hope this helps,

• Non-linear curve fit (distribution of blackbody radiation)

  Hello

  In my measurements I would estimate the temperature from the spectra of light emitted through the Planck law of the distribution of the black body radiation. I tried to get my data with non-linear curve fit, but I encountered some problems:

  1.) function is not properly, because of the distribution of different adjusted data form and input data values.

  (2) when tracing distribution of Planck by using the best shape parameter, the plot is different from the theoretical distribution of given temperature. (My data comes from the source of temperature 3100K, best setting made is 1130K, but fit is different from the theoretical distribution of 1 130 K)

  

  When I get a few simple equations, everything works, so I'm not sure of what could be a problem.

  Many thanks for any advice.

  Ivan

  Quickly, giving once more on this, it seems to me that one of your constant if four orders of large magnitude.

  You get a very good fit with 3.74177E - 16 instead of 3.74177E-12, see picture. (You divide your theoretical curves by 10000, but you aren't in your formula!)

• Reference to only part of a story?

  Hi guys,.

  In VB, I used the following to be able to find the cursor at the end of a story.

  Set Ind.Selection = Schär (1). ParentStory.Characters (Ind.Selection (1).) InsertionPoints(-1). Index)
  EChar value = Ind.Selection (1). ParentStory.Characters(-1)
  Set SrchTxt = Ind.Selection (1). ParentStory.Texts.ItemByRange (Schär, EChar)

  I'm assuming that I would be able to browse the SrchTxt.Paragraphs also, but whatever the object type SrchTxt ends up being is not 'Paragraphs' as a property.

  I want to iterate through a part of history by paragraph and according to certain criteria, one of them being the style applied to the paragraph, stop if the user performs the action.

  How to refer to only part of a story, or understanding, in which the paragraph in a story, the cursor is planted the script at startup?

  Thank you very much

  Ken

  Hi Ken

  As substances said - you need to refer to the first element of the result of ItemByRange.

  And you are not limited to the characters as params. Texts.ItemByRange(start,end) - you can use any text, start, end - PointInsertion object, character, Word, etc. - but you can not use some numbers-text is only by each text element

  If you need to refer to the "current": paragraph

  Set myCurPara = myInDi.Selection.Item (1). Paragraphs.Item (1)

• Non-linear curve Fit error 20068?

  Trying to do a simple 3-exponential decay curve nonlinear.  I have a copy of this work in the other screws, but it doesn't seem to work in this VI.  I use "Scalablemultiexponentialdecay" of Altenbach as a VI/template model.  Data that I'm trying to adapt are a series simple decomposition RC, yes I realize that should not have 3 exponential components, it's just the model data.  I am able to adapt with the Fit exponential function built in to the Math palette, but which only works if the input bounds parameter is wired and with rational constraints.  However, I get an error on the adjustment of the non-linear curve that I understand not (photo attached) indicating that an INF or NaN is done in the settings.  I don't see where this is going...

  Any questions or help is appreciated.

  

  

  I thought so, only 0 s for the 2nd two exponentials.  But, if I replace all the guess seededes with the same as the simple exponential Installer, it converges without error.   I guess I didn't know it was that sensitive.  Thank you.

• When I try to print a page, I get the entire page of very low, either I get only part of the page. Which setting I'm missing?

  I am trying to print a page of a web page. If I check, 'reduced to fit' print / page setup, I get the whole page but small enough to be useless. If I uncheck 'reduced to adjust', I get only about 1/3 of the page. I tried the % function, and it only changes the size of the narrow portion I see already. How to print the whole page in a reasonable size?

  If Firefox does not use the entire sheet of paper, it can result from Firefox after having extracted the Windows incorrect paper size settings when reading data from the print driver. Compensation it may involve conclusions some mask parameters, but here goes:

  (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (2) in the search above the list box, type or paste print and make a pause so that the list is filtered

  (3) for each parameter which specifically mentions the problem printer, right click and reset The fastest way is to click with the mouse and press the r key on the keyboard with your other hand.

  Note: In a few discussions involving Brother printers, printer_printer_name.print_paper_data preference was established in 256 and when the user changed it to 1 which, in itself, solve the paper size. If you are using a Brother printer and see a 256 here, you can change the value by double-clicking it or by using the right click > modify.

• Non-linear curve fit the model of reference file

  Hello.

  I use the VI of the non-linear curve adjustment in order to adapt the data. The reference to the fitting VI model I use is included in the attachment. You can see that I have a few constant wireline, like 4, 2500 and 1. I want to do this constant variables I'll change before each curve corresponds, because actually in my problem this variables I know before the adjustment and they are constantly changing, and for the moment this made VI just to test.

  The problem I have is that I can't enter the values of this variable to my main VI, where I also call the VI was nonlinear. The scheme of connection of refernce VI made must be changed in order to be recognized by the VI was nonlinear. I tried to use a table to transfer variables, but if I use one, it recognizes the variables as parameters of editing and he's trying to install as well in the adjustment process, and it gives me erroneous results.

  Any ideas how I can add the values of variables?

  Thank you very much.

  Kind regards

  To provide additional data randomly in VI of model, you must use the entrance of 'data' (it is a variant and so can contain anything you want!). Just create any type of data you want (generally a cluster if there are several values of different data types) that contains all the values, convert them to a Variant in the main VI and the variant of wire to crimp her. In the model, you convert the variant return to data, to the constant help of cluster, such as defined in the main as VI 'type' (simply right click cluster in the main VI... wire Create constant... move the constant in VI of model). Now, to unbundle the different values and use them anywhere inside your model.
