function c = r8ltt_mtm ( n, a, b )

%*****************************************************************************80
%
%% R8LTT_MTM computes C = A' * B, where A and B are R8LTT matrices.
%
%  Discussion:
%
%    The R8LTT storage format is used for an N by N lower triangular Toeplitz
%    matrix.
%
%    Note that the result C is a dense matrix, of type R8GE.
