MATLAB: How to merge two arrays/rearrange two table colums one by one

Question

Let's say I have tow arrays both are horizontal with the same size like:

A=[1,2,3,4,5];

B=[11,22,33,44,55];

I want to merge them so that the final array would be:

AB=[1,11,2,22,3,33,4,44,5,55];

This was my first question. And the second question is similar to the first one so that I have (one row of the table):

table=[1,2,3,4,5,11,22,33,44,55] and I want to rearragne table columns so that I would have:

table=[1,11,2,22,3,33,4,44,5,55];

Answer 1

AB = reshape([A; B], 1, [])
