How do I create such matrix ? (please look at the thread for further details)

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?

A=[1 2 3;4 5 6]
B=[11 22 33;44 55 66]
C=[111 222 333 ;444 555 666]
[n m]=size(A);
p=3 % number of variables;
A=A';
B=B';
C=C';
out=reshape([A(:) B(:) C(:)]',m*p,[])'

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!
