Hi,
I am trying to find the colums and rows in a large matrix that contain the submatrix.
Say we have
T = [0,3,0,0,0,0;3,0,4,0,8,0;0,4,0,1,0,0;0,0,1,0,0,0;0,8,0,0,0,6;0,0,0,0,6,0]
0 3 0 0 0 0
3 0 4 0 8 0
0 4 0 1 0 0
0 0 1 0 0 0
0 8 0 0 0 6
0 0 0 0 6 0
and we have a submatrix of
S = [0,3,0,0;3,0,4,0;0,4,0,1;0,0,1,0]
0 3 0 0
3 0 4 0
0 4 0 1
0 0 1 0
how can we find the rows and columns in T that contain submatrix S please?
TIA
