I have some problem to ask you about DCT processing on matrix data.
I can find only dct for image processing only, but no for matrix processing.
I have a matrix like
1 2 3 1
4 5 6 2
7 8 9 3
**** This matrix is not Image matrix.
So, if I want to do DCT on this matrix to reduce from 3X4 to 3X1.
Is it possible to do?
