Hello! I have a function which generates a matrix M containing elements. Some of them are infinite (- Inf for example). I need to extract the minimum finite value of M, but if I write min(M) I obtain of course - Inf. What command can I use ? Thanks

min(M(~isinf(M))

As are you are concerned about the global mean, you truncate the Inf elements and compute the min:
M(isinf(M))=[];
min(M)
