Multidimensional Discrete Cosine Transform (DCT) (Scripts) Publisher's description
from Andriy Myronenko
The function is much faster than Matlab's native (dct, idct, dct2, idct2)
The function is much faster than Matlab's native (dct, idct, dct2, idct2). It also allows N-D (multidimensional) input.
y=mirt_dctn(x); % forward DCT
x=mirt_idctn(y); % inverse DCT
