how can i get an inverse normal distribution probability function value?

what is its code in MATLAB?

If you have the Statistics and Machine Learning Toolbox -- Inverse Gaussian Distribution.

For example,

pd = makedist('InverseGaussian');

x = 0:0.1:5;
y = pd.pdf(x)
figure; plot(x,y,'.')

I don't think this is correct.

norminv computes the inverse of the cdf of the normal distribution. I believe that the question is about the inverse normal (or inverse Gaussian) distribution, which -- despite the confusingly similar names -- is a different thing.

The question is ambiguous. It might be about either.
