Matlab: Matrix with negative numbers

I have a matrix, A = [745 x 678], which consists of negative and positive values. I would like to make all the negative numbers zero but am not sure how to go about doing this.
I was thinking of something like:
n = 678
for i = 1:n
A(A<0) = 0
end
I am not sure to how to apply this to every element of the matrix though. Any help would be appreciated.

Hi,
you do not need to iterate over all the elements of a matrix to do so, you can simply do this:
m = [1 2 -1; -2 4 -7; 9 -5 1];
m(m<0) = 0 ;
this will give you
m = [1 2 0; 0 4 0; 9 0 1]
