`functional_create_dct.Rd`

Create a DCT transformation matrix with shape (`n_mels`

, `n_mfcc`

),
normalized depending on norm.

`functional_create_dct(n_mfcc, n_mels, norm = NULL)`

- n_mfcc
(int): Number of mfc coefficients to retain

- n_mels
(int): Number of mel filterbanks

- norm
(chr or NULL): Norm to use (either 'ortho' or NULL)

`tensor`

: The transformation matrix, to be right-multiplied to
row-wise data of size (`n_mels`

, `n_mfcc`

).
