Creation of matrix (72,1) by defined elements

Hello. I have three matrices (24,1): Pstmax(24,1), Pproda(24,1), Pprodb(24,1), and i want to create a matrix ub(72,1) that contains the elements of the three defined matrices as follow:

Best regards.

Answer 1

ub = reshape([Pstmax,Pproda,Pprodb].',[],1)

or if they could be row vectors:

ub = reshape([Pstmax(:),Pproda(:),Pprodb(:)].',[],1)

This works:

Pstmax = randi(99, 24, 1);
Preproda = randi(99, 24, 1);
Preprodb = randi(99, 24, 1);

Prevct = reshape(reshape([Pstmax; Preproda; Preprodb], [], 3)', [], 1);
