% @deftypefnx {Function File} @var{y} = dst (@var{x}, @var{n})
% Computes the type I discrete sine transform of @var{x}. If @var{n} is given,
% then @var{x} is padded or trimmed to length @var{n} before computing the transform.
% If @var{x} is a matrix, compute the transform along the columns of the
% the matrix.
%
% The discrete sine transform X of x can be defined as follows:
%
% N
% X[k] = sum x[n] sin (pi n k / (N+1) ), k = 1, ..., N
% n=1
