How would I write a for loop to extract columns from a large matrix and put it into a new matrix. For example, I want to take every 6th column of my very large matrix and store it in a new matrix.
Thanks!

No loop needed:
a = your very large matrix
b = a(:,1:6:end); % every 6th column, starting with 1st column
