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 |
