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?

If A is your matrix:
A(A(:,1)==0,:)=[]
