idct

Version:
    Last Modified: March 15, 2017

    Computes the inverse discrete cosine transform.

    Syntax

    c = idct(a)
    c = idct(a, b)

    Inputs

    a

    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.

    Outputs

    c

    Inverse discrete cosine transform of a.

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