How to remove zero sum row from matrix
显示 更早的评论
A=[1 2 3 4 5 6;
0 0 1 1 0 1;
0 0 1 0 1 0]
Sum of second and third row if equal to zero, then in new matrix that column is to be excluded. So, the result shall be
A=[3 4 5 6;
1 1 0 1;
1 0 1 0]

Edited my answer so that it will sum all rows except the first one.
