Suppose i have a column vector A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}; What command can I use to extract every two succesive rows of vector A and turn them into columns to create matrix B = { 2 6 10 14 18, 4 8 12 16 20};?

I think the easiest way to do this is to use reshape function to
make A a 5x2 matrix and then transpose it.
A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}; /* ** 1. Use 'reshape' to make, B ** 2 4 ** 6 8 ** 10 12 ** 14 16 ** 18 20 ** ** 2. Transpose the result of step 1. */ B = reshape(A, rows(A), 2)';
