Hi, I have a vector and a matrix. For example, A = [ 12 3 4]; B = [ 4 13 10 2 4 8]; I am comparing A to each column of B using A>B[,ii], so the expected result is C = [ 1 0 0 1 0 0];
This list is about R rather than Matlab dialects. For R: A>B gives logical values and, e.g., apply(A>B, 2, as.integer) converts to integer. Uwe Ligges
I am looking for a way to do this quickly instead of going through the for loop, but haven't had any luck yet? Any advice is appreciated. Thank you very much.
