//x: real or complex valued vector
//n= Length to which x is trimmed before transform 
//Description
//This is an Octave function.
//Computes the type I discrete sine transform of x. If n is given, then x is padded or trimmed to length n before computing the transform. If x is a matrix, compute the transform along the columns of the the matrix.
