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]
