minimum of a matrix

Hi everyone,

In my code I have 3 dimensional matrices and I need the overall minumum of this matrix.

Right now I use : min(min(min(matrix)));

This works fine, but I wonder if there is a function in MATLAB which calculates the minimum of the entire matrix.

The "trick" is not in using a certain command, but to know that your 3 dimensional matrix can be addressed as a vector. Example:

a=rand(2,2,2)
a(:)
min(a(:))

Thanks so much, I thought I had seen it in codes I have used before, but I couldn't figure out how to do it
