How to sort vectors so every 1 entry is collected and followed by every 2 entry until the nth entry

Say you have m vectors on the form a=[a1,a2,...,an]

is it then possible to sort them into the following vector:

s=[a1,b1,...,m1,a2,b2,...m2,...,an,bn,...,mn]?

edit: added the dots in bn,...,mn

Answer 1

[Roger Stafford]

s = reshape([a;b;c;...;m],1,[]);

thank s a lot, that's much smarter than what i was doing
