How can I remove an entire row of zeros in a matrix?

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

Answer 1

[David Fletcher]

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
