Hi,

I want to extract a slice of a 2D matrix from a bigger 2D matrix with certain values. So, if I have a matrix as follwoing:

M = [1 2;
4;
1
1
3
4
0
0];

And I want to extract a slice

that only has values in the second column equal one.

Any help would be appreicted.

Thanks.

4;
1
1
3
4
0
0];
y = M(M(:,2)==1, :)
y = 2×2
   1
   1
