% Concatenate two matrices regardless of their type. Due to the implementation
% of the matrix concatenation in Octave being hard-coded for the types it
% knowns, user types can not use the matrix concatenation operator. Thus
% for the @emph{Galois} and @emph{Fixed Point} types, the in-built matrix
% concatenation functions will return a matrix value as their solution.
%
% This function allows these types to be concatenated. If called with a
% user type that is not known by this function, the in-built concatenate
% function is used.
%
% If @var{dim} is 1, then the matrices are concatenated, else if @var{dim}
% is 2, they are stacked.
