vertcat

description:

A = vertcat(varargin) performs vertical concatenation. vertcat(A,B) or [A;B] is the vertical concatenation of matrices A and B. A and B must have the same number of columns. Any number of matrices can be concatenated within one pair of brackets.

arguments:

matrices of NCpolys with the same number of columns

output:

matrix of NCpolys

possible usage:

[A1;A2;...;An], vertcat(A1,A2,...,An)

examples:

>> A=[x y;-y x^2]

A = x     y

   -y   x^2

>> [A;A]

ans = x     y

     -y   x^2

      x     y

     -y   x^2
