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)';
