How can I generate a gauss function?

[zäpfle]

Hello together,

I would like to generate a Gauss function. Is there a SubVI. I tryed it, with the SubVI "Gauss Function.vi", but without success.

I hope anybody can help me.

Thanks

It works fine.

What do you mean by u failed??

What r ur expected input & outputs???

Try "gaussfir (MathScript function)"...i think this is what u r looking for.

Spaetzelcountry,

i assume that you want to display a Gaussian Distribution.

If so, pleas take a look into the example finder and search for Gauss.....

hope this helps,

Norbert

Yes I mean a Gauss distribution.

Hello Kekin,

It is possible that you post a example with the "Gauss Function.vi"?

Hello Norbert B,

I looked into the example finder and found: "Gauss Mod sin Generation.vi". Do you mean there is a easier way (VI)?

Thanks a lot

hi zapfile,

  I am posting the gaussian function i.e exp(-x^2/2).

Thanks and regards,

Where can I find this VI?

[kekin]

The VI is under Math->Probability&statistics.

Thanks a lot an everybody

I had the same problem. I found a good solution:

In the end I used the "Gaussian-Peak-Fit.vi"  . It has an input "parameter bounds"; this has to be set to the 4 parameters that define your desired gauss function (center, amplitude, width, offset).

The parameter bounds needs a max and a min-value for each parameter. I just set max=min. (see diagram: 4 values in and 8 values out as a cluster).

The data feed into the Y-input is irrelevant. It is only necessary so that the gauss-fit routine does not complain.

The inspiration for this solution came from the following statement in the help of the Gaussian-Peak-Fit.vi:

"If you know the exact value of certain parameters, you can set the lower and upper bounds of the parameters equal to the known values."

Here is a nice programm:
