Examples
idct1([1,3,6]) ans = 5.1481604 - 4.3216292 0.9055197 |  |  |
Compute the inverse discrete cosine transform of input.
Y = idct1(X) Y = idct1(X, N)
Matrix or integer
If N is given, then X is padded or trimmed to length N before computing the transform.
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.
