MATLAB: How to clear out rows of zeros in a matrix

Question

Hello,

I am trying to get rid of all rows of zeros of this Matrix.

162  1
0  0
202  1
0  0
296  1
0  0
447  1
0  0
481  1
0  0
489  1
0  0
525  1
0  0
539  1
0  0
724  1
0  0
732  1
0  0

The output should be like this:

162  1
202  1
296  1
447  1
481  1
489  1
525  1
539  1
724  1
732  1

I have tried several ways, but I keep getting errors. Can anyone help me out?
