I have a matrix not a vector and I need the minimum value except 0 and position of minimum value in each row

a=[8,2,3,4,5];
[b,ix]=min(a);
ix gives you the positions and b gives the minimum value

Your question has been answered, so you should accept the answer.
As for your program, it has no comment and you haven't even said what is wrong with it or what it's supposed to do. What are we supposed to correct?
Your program is just a convoluted way of doing
mm = m(:)';
Is that the correction you're looking for?

To find the minimum of a row, use:
min(m, [], 2)
Probably, the simplest way to ignore 0s is to replace them with NaNs before calling min.
m(m == 0) = nan;
[mval, mcol] = min(m, [], 2);
