function y = idct1(x,n)
//Compute the inverse discrete cosine transform of input.
//Calling Sequence
//Y = idct1(X)
//Y = idct1(X, N)
//Parameters
//X: Matrix or integer
//N: If N is given, then X is padded or trimmed to length N before computing the transform.
//Description
// This function computes the inverse discrete cosine transform of input 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. The transform is faster if X is real-valued and even length.
//Examples
//idct1([1,3,6])
//ans =
// 5.1481604 - 4.3216292 0.9055197
