[per isakson]

The matrices must have the same number of rows and have values of the same class.

len = 7;
A1 = ones( len, 2 );
A2 = 2*ones( len, 5 );
M = cat( 2, A1, A2 ); % or shorter [A1,A2]
whos M

returns

Name      Size            Bytes  Class     Attributes
M         7x7               392  double
