Hi,

Let say I have a matrix of [X1 X2 ... Xm], [Y1 Y2 ... Ym] and [Z1 Z2 ... Zm].

All mentioned matrix have m column and n row each, how do I make it in such a way that it becomes [X1 Y1 Z1 X2 Y2 Z2 ... Xm Ym Zm] that gives 3m columns and n rows matrix?

help cat
help vertcat
help transpose
help reshape

After reading about those functions you should be able to do it yourself and learned a lot along the way. Just try (and fail and try and fail and try …) and succeed!
