[Scilab-users] Re : concatenate hypermatrices along the 3rd dimension

[sgougeon at free.fr]

Hello Antoine,

Please check cat(3, ..) to concatenate along the 3rd (or any) dimension.
Please check resize_matrix() to padd an hypermatrix (with what you want).

Regards
Samuel

Objet: [Scilab-users] concatenate hypermatrices along the 3rd dimension

Hi all,

I'm trying to stack (or concatenate) 3D matrices (hypermatrices) along 
the 3rd dimension.
(The goal is to perform zero-padding along the 3rd dimension).
So far, the only - and ugly - solution I've found is the following:

//my padding
a=zeros(2,2,3);
//my data
b=a;
b(:,:,1)=[111,112;121,122];
b(:,:,2)=[211,212;221,222];
b(:,:,3)=[311,312;321,322];
// zero-padded data
padded_b=matrix([a(:);b(:);a(:)],[size(a,1),size(a,2),3*size(a,3)]);
Is there a solution that is less convoluted (and maybe more efficient) 
than resorting to this mix of "(:)" and "matrix"?
