Dear all, I have a column matrix A and an nxn matrix B. I have been able to estimate the correlation coefficient (R) between the constant column matrix A and each column vector in matrix B using corr(A,B). However, I am finding difficulties in summing only columns with their R=>0.2, while ignoring columns with R<0.2. I will be very grateful for the assistance.
