Reductive example.
Assume this is your matrix
A = rand(10,5)
and let's assume your logical criteria is that you want to extract all the values in column 3 and 5 that correspond to values in column one which are greater than 0.5.
Then you simply do
b = A(A(:,1) > 0.5,3) % extracts values from 3rd colum that correspond to values > 0.5 in the first column
c = A(A(:,1) > 0.5,5) % extracts values from 5th colum that correspond to values > 0.5 in the first column
You can easily apply these indexing criteria to your case.
