Hi,
I have a 2D array with positive value in the 2 column.
What I want to do is to find the positive value of each column.
For example, I have this array
A B
-1 1
2 -2
3 9
5 4
-5 6
6 7
and I want to obtain the following
A B
3 9
5 4
6 7
I manage to have the positve in each case but the value do'nt correspond (I have all the positive value of each column) like
A B
2 1
3 9
5 4
6 6
7
can you help me please ?
