Function Synopsis

a = idct(b,n)

Help text

IDCT	Inverse discrete cosine transform.

	X = IDCT(Y) inverts the DCT transform, returning the
	original vector if Y was obtained using Y = DCT(X).

	X = IDCT(Y,N) pads or truncates the vector Y to length N 
	before transforming.

	If Y is a matrix, the IDCT operation is applied to
	each column.

	See also: FFT,IFFT,DCT.
