function C = trans (arg1, arg2, arg3, arg4, arg5)
%GRB.TRANS transpose a sparse matrix.
%
% C = GrB.trans (A)
% C = GrB.trans (A, desc)
% C = GrB.trans (Cin, accum, A, desc)
% C = GrB.trans (Cin, M, A, desc)
% C = GrB.trans (Cin, M, accum, A, desc)
%
% The descriptor is optional. If desc.in0 is 'transpose', then C<M>=A or
% C<M>=accum(C,A) is computed, since the default behavior is to transpose
% the input matrix.
%
% For complex matrices, GrB.trans computes the array transpose, not the
% matrix (complex conjugate) transpose.
%
% See also GrB/transpose, GrB/ctranspose, GrB/conj.
