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,'.')

y = normpdf(x) returns the probability density function (pdf) of the standard normal distribution, evaluated at the values in x.

For example

Compute the pdf values for the standard normal distribution at the values in x.

x = [-2,-1,0,1,2];
y = normpdf(x)

y = 1×5

    0.0540    0.2420    0.3989    0.2420    0.0540
