Hey,
I have a matrix D and I would like to compare columns elements with each other with a conditional non-zero statement: if only one element in a row is > 0 then keep all zero values in that row 0 and make the nonzero value 1. In addition, if more than one element in a row is nonzero then make all elements in that row 0.
I really appreciate the help!
Many thanks!
Felix
A = [6;3;4];
B = [2;0;1];
C = [6;0;3];
D = [A,B,C]
D =
6 2 6
3 0 0
4 1 3
% desired result
E =
0 0 0
1 0 0
0 0 0

D =[
6 2 6
3 0 0
4 1 3];
out = D > 0;
out(sum(out,2) > 1,:) = 0;
