Unable to run code due to an error in 'Fadeeva_m' function

Hi guys, I have some data for my project and I wanted to fit the Voigt function to the data, since I am so new to matlab and fitting I wanted to use an example: Voigt fitting

When I wanted to run this code with my data with the following way:

data = readmatrix("labdatacopy.csv");
data = data(9:end,:);


y = data(:,4);
x = data(:,1);

initGuess1 = [46, 0.5, 0.5];
[estimates1, model1] = voigtfit(x, y, initGuess1, [40, 50]);
disp('Single peak fit results [peak1, gamma1, sigma1]');
disp(estimates1);

I get following error:

I tried download other packages which contain Fadeeva_w function, however error still there.

Do you have any recomendations?

you need to run the build script to compile faddeeva_w

Thank you for your answer , however it didn't work as well.

Execution of script Faddeeva_w as a function is not supported:

[Walter Roberson]

You need to have configured a c++ compiler and executed

Faddeeva_build

That will compile the c++ source code into something that will take precedence over the .m file
