Member of the transforms class.

Syntax

c = idct(a)

c = idct(a, b)

Computes the inverse discrete cosine transform.

Name	Description
a	Specifies the 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.
b	Pads a with zeros or truncates a to length b. b is a positive integer.

Name	Description
c	Returns the inverse discrete cosine transform of a.

x = cos(0:12);
y = idct(x, 16)
