find minimum value greater than zero in the rows

a=[9,32,7,0,0,0,0,0;15,32,9,0,0,0,0,0;25,42,0,0,0,0,0,0];i have to find out minimum value in 'a' which should be greater than zero.my answer has to be b=[7;9;25].suggest some points

Answer 1

[Andrei Bobrov]

a(a == 0) = inf;
b = min(a,[],2);

I think you mean

a(a <= 0) = inf;

so that the code can handle elements of a that might be less than zero also. It's just more general since he didn't specify the range of values that a might have.

Thank you sir

[Andrei Bobrov]

Thank you Image Analyst! I agree with you.

Answer 2

The min command plus

a(a<=0)=nan;
