Description
~~~~~~~~~~~

The MATCATH Block outputs the horizontal concatenation of multiple
matrices. It is also called concatenation according to the columns.
The inputs U1,U2,...,Un must have the same number of rows. The user
must set the number of input matrices in the **Number of input**
parameter.

The output is a M-by-(N1+N2+...+Nn) matrix, where N1,N2,...,Nn are the
numbers of columns of the inputs matrices, and M is the number of
rows.

The equivalent of MATCATH in Scilab is y=[U1 U2 ... Un].





Dialog box
~~~~~~~~~~






+ **Number of input** It indicates the number of input matrices.
  Properties : Type 'vec' of size 1.




Example
~~~~~~~


::

    A=[1 2 3;4 5 6]
    B=[7 8;9 10]
    The result of the horizontal concatenation is:
    C=[1 2 3 7 8;4 5 6 9 10]
