## @deftypefn {Loadable Function} {} reshape (@var{a}, @var{m}, @var{n})
## Return a matrix with @var{m} rows and @var{n} columns whose elements are
## taken from the Galois array @var{a}. To decide how to order the elements,
## Octave pretends that the elements of a matrix are stored in column-major
## order (like Fortran arrays are stored).
##
## For example,
##
## @example
## reshape (gf([1, 2, 3, 4],3), 2, 2)
## ans =
## GF(2^3) array. Primitive Polynomial = D^3+D+1 (decimal 11)
##
## Array elements =
##
## 1 3
## 2 4
## @end example
##
## The @code{reshape} function is equivalent to
##
## @example
## @group
## retval = gf(zeros (m, n), a.m, a.prim_poly);
## retval (:) = a;
## @end group
## @end example
##
## @noindent
## but it is somewhat less cryptic to use @code{reshape} instead of the
## colon operator. Note that the total number of elements in the original
## matrix must match the total number of elements in the new matrix.
## @end deftypefn
## @seealso{`:'}
function varargout = reshape (varargin)
varargout = cell (1, max(1, nargout));
[varargout{:}] = greshape (varargin{:});
