Computes the inverse discrete cosine transform.
c = idct(a)
c = idct(a, b)
Input array. a is an array. If a is a 2D array, idct computes the inverse discrete cosine transform along the first non-singleton dimension of a.
Pads a with zeros or truncates a to length b. b is a positive integer.
Inverse discrete cosine transform of a.
x = cos(0:12); y = idct(x, 16)
