显示 更早的评论
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;
1 4;
7 1
9 1
0 3
0 4
9 0
8 0];
And I want to extract a slice 
that only has values in the second column equal one.
that only has values in the second column equal one.Any help would be appreicted.
Thanks.
