I want to use the following function Y = normpdf(X,mu,sigma)
X is a vector of 100*1 for each X I have a mu and a sigma , do you know how to do that ?

So what is the problem? You have a vector X, a vector mu and a vector sigma and a function that expects all these as inputs.

From the documentation for normpdf at
http://www.mathworks.com/help/stats/normpdf.html
"Y = normpdf(X,mu,sigma) computes the pdf at each of the values in X using the normal distribution with mean mu and standard deviation sigma. X, mu, and sigma can be vectors, matrices, or multidimensional arrays that all have the same size. A scalar input is expanded to a constant array with the same dimensions as the other inputs. The parameters in sigma must be positive."
That should answer your question.

Thanks but I knew this, my question is something different from what you just said
