9MEL filters are represented as 3 arrays to encode a sparse matrix.
10
11.. autofunction:: cmsisdsp.mfcc.melFilterMatrix
12
13The API is returning a tuple::
14
15  (filterLength,filterPos,PackedCoefficients)
16
17The first argument is the list of MEL filter lengths.
18
19The second argument is the position of the first coefficient of the filter in the list of coefficients,
20
21The last argument is the concatenated list of all filter coefficients.
