How to find elements of first matrix based on second matrix?
이전 댓글 표시
I have two matrices A and B
A = [1 2 3 4 5 6 7 8 9 10];
B = [1 0 0 1 0 1 0 1 1 1];
How to find entries of A coresponsing to '1' in B
result = [1 4 6 8 9 10];

Note that FIND is not required, logical indexing is simpler and more efficient:
A = [1 2 3 4 5 6 7 8 9 10];
B = [1 0 0 1 0 1 0 1 1 1];
C = A(B==1)

use find function
A = [1 2 3 4 5 6 7 8 9 10];
B = [1 0 0 1 0 1 0 1 1 1];
result=A(find(B==1))
