Need help with the non-linear curve - fit

Hello

"I enclose you a VI that calls the function of nonlinear smoothing" Lev - Mar "with two slightly different formulas.

On my machine (Win7, LV2011) adjustment is a straight line when bool example FP is set to FALSE.

This is expected behavior?

Is it possible to get a good fit, with the coefficient of 0.97 and _without_ increase in the number of points?

Thanks in advance!

I've just implemented the formula to the fitting VI.  I did not review the calculation you did for "raw" data

Review: The first value of x is equal to zero. To get a phase shift of ~pi/2 a good first guess for c is 1.57.  With a value close to that, it gives a good fit for each choice of c.

  • apply restrictions for the non-linear curve fit

    Hello Forum users,.

    I am currently working on a VI control which is supposed to create a specific model of pressure inside a hollow tube to provide a test environment for pressure sensors. The details are many and complicated, so let's say I am sure that my formula to calculate this profile according to the pressures inside the hollow rings around this tube will work.

    To find the correct pressure for each ring values, I've linked to a model VI containing this form to Lev. - Mar algorithm (the non-linear curve adjustment) and let it run.

    Technically, there is no problem and Lev - Mar find values to adjust the function for the values (not perfectly sure, but close enough).

    The problem is, however, that, since the device, once suitable values for the positioning and size of the rings are found, must be built, the simulated pressure rings perhaps intersect not between them. To apply this rule, I added a check to my VI of model and if the values passed to Lev - Mar breaking the rules, the VI model gives a matrix of zeros to follow him (I tried an empty array, but that only leads to error messages).

    This solution did not work. Lev - Mar seems to ignore these cases always looks for values that break my rules (and if I put these values through my model VI, I get a matrix of zeros, as expected, so the audit seems to work).

    Perhaps I misunderstood the algorithm of Lev - Mar and it does not actually check each possible defined coefficients of finds.

    Is it possible to adapt to any function of a set of values while keeping the predefined boundary conditions?

    Oh, before I forget:

    I use LabVIEW version 8.2 in the Institute, because the workshop systems is not installed 8.5 for some reason any.

    Thanks in advance

    Hi Thaliur,

    Thanks for posting on our forums.

    I understand your request you expect the algorithm to ignore a case to all zeros in the table. However, it is not implemented like this.

    Good news is, its source code can be edited and you could save your own personalized version of the algorithm of screws it is to you that you just add a check for a matrix of zeros or simply pass another parameter which indicates only a case of "broken rules". Then you would not have to continue the calculation.

    If I misunderstood your question, please clarify this. You can also post a code for further explanation, if you wish.

    Good luck with the project!

  • 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.

  • 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.

  • 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.

  • 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!)

    I do some corn on the COB for an illustration and I need help with the texture of the ball.

    I've been slowly making progress with gradient for kernels mesh, but I can't seem to recreate the look of the ball at all.

    Tank,

    You have published three images stylistically very different. The first is photographic and call probably (but not necessarily) for graduates of mesh. The other two are graphical treatments (and frankly, they're both rather flat; lack of depth).

    Illustration style extends the range of cartoonish in sketchy photo-realism and all the rest. The problem is you didn't show your own attempt so that anyone can have an idea of what you're trying to achieve the stylistic point of view.

    I just need to put in place so that the final step does not appear the whole box. The problem now is trying to make the style of the good brush to reproduce the effect...

    You seem to think you have to build a kind of linear construction and then find a way to reshape the shape of each part of the leaf. Yes, you pouvez approach it this way, but Illustrator users has often tend to be what aunt Molly would call "too clever by half."

    Not everything must be something semi intelligent auto or complex and tedious consruct involving brushes, envelopes, masks, etc, etc. Much can be accomplished by thinking that he just thanks to measure you draw directly economic paths and constructions, which take no more time (often less) and result in very tidy, simple files. Again, a lot depends on what you are trying to achieve the stylistic point of view. But here's an example that only took a few minutes to draw:

    If the above consists of:

    Three roads closed, 8 points each, with ordinary linear degrees

    Three mixtures of open path with three anchor points for each key path

    Six paths closed for shadows / highlights, with 19 points in total

    Mixtures being directly from the paths drawn comic forms, the spacing of the veins 'automatically' and intuitively follows the width from point of view of the worksheet.

    Rather than to build a boilerplate brush, colouring and the weight of each of the three main paths of the vein mixtures can be set individually at any time, simply directly by selecting the key path.

  • Hello need help with the opacity mask.

    Hello need help with the opacity mask. I hope someone out there can help

    I inherited a logo that appears to use a Logo of OM has a shape with a grad. This grad at first sight is not used in the Grad scheme and there is not editable.  Looking at the transparency palette I find an OM (pic1) output option. If I choose what the grad on separates it from the page of the form, that is from there I can change/remove as required (Note2).

    However, sometimes (he did no change), I'll be back to the same original form and output option is grayed out and is no longer available. Or I go to the similar shape that has the same treatment and I can't go out OM (pic3)

    The only difference is the thumbnail in the transparency palette, which is strong in pic1 and rated on pic3. What Miss me?    I'm not clear what the advantage is simply OM using the Grad palette to apply a grad in my form, but until I can get rid of OM who is there, I can't comfortably apply to the grad I want.

    The white gradient LHS I have no problem with. I choose fortunately only and each time get the possibility of release of OM.

    The other thing weird. When I select the white gradient. Sometimes, the exit option is in the palette without going through the drop-down list (Fig 4).

    Other times seems not that OM has already been applied, because the palette gives me the ability to mask rather than liberation (5 photos). Until I go to the drop down and then I find Release is an option after all.

    What is the difference here?   Not much of a problem, because either way I can release OM to be able to change the grad.

    The file is passed through several hands and play anywhere to try to resolve issues, and many stops and save slot, so something along the line was of course done a logo and not the other because of the difference, but I can't for the life of me see what that.
