MATCATH

Horizontal Concatenation

Block Screenshot

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]
