MATLAB: How to remove an entire row of zeros in a matrix

delete rowmatrixzeros

If I have a matrix like this one:

 45 23 54
 0  0  0
 9  3  32

How can I remove the second row and obtain this matrix?

45 23 54
9  3  32

a=[45 23 54;0  0  0;9  3  32];
zero=a==0;
ind=all(zero,2);
a(ind,:)=[]

Presumably the entire row has to have zero in every column for it to be removed

A = [36    13
     9    21
    23    32
    35     5
     3    43]
B = A([1,3,5],:)

b = sortrows(a,2);
