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

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

The output is a (M1+M2+...+Mn)-by-N matrix, where M1,M2,...,Mn are the
numbers of rows of the inputs matrices, and N is the number of
columns.

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





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






+ **Datatype(1=real double 2=Complex)** It indicates the type of the
  output. It support only the two types double (1) and complex (2). If
  we input another entry in this label xcos will print the message
  "Datatype is not supported". Properties : Type 'vec' of size 1.




Example
~~~~~~~


::

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