Hey
I have a matrix A of 34x2 double.
I want to eliminate the rows wherein the value of both the columns is 0.

What?
>> A = [1,2; 0,0]
A(all(A == 0, 2), :) = [ ]
A =
1 2
0 0
A =
1 2

Hello Madhan,
Extremely sorry I actually made an error earlier in the loop which lead to me not getting the right answer. Thanks a lot for the solution. It worked perfectly.
