Execution of script Faddeeva_w as a function is not supported:

Tryying to apply Voigt Model Fit generates the error

[estimates, model] = voigtfit(x, y, initGuess, peakBounds)

Execution of script Faddeeva_w as a function is not supported:

C:\Users\t.pagel\AppData\Roaming\MathWorks\MATLAB Add-Ons\Collections\Faddeeva Package_ complex error functions\Faddeeva_w.m

Error in voigtfit>voigt (line 129)

vp = (1/(sig*sqrt(2*pi))) * real(Faddeeva_w(z)); % Get Voigt from Faddeeva fn.

Error in voigtfit>calc_model_from_nlparams (line 162)

A(:,k) = voigt(x, nlpVec(3*k-2), nlpVec(3*k-1), nlpVec(3*k));

Error in voigtfit (line 80)

peaksCell = calc_model_from_nlparams(initGuess, xdata, ydata);

the model has nbeen added correctly to matlab.

What is the problem?

[Dyuman Joshi]

You have defined the file "Faddeeva_w " as a script.

But you are trying to call it as a function i.e. by providing an input (as the error has highligted), which is not allowed.

Modify the file to define it as a function which accepts an input and provides output(s) as required.

For reference, see - function.

You need to first execute

Faddeeva_build

to configure the remaining functions for use with your system.
