determ - determinant of polynomial matrix
8
W : real square polynomial matrix
10
k : integer (upper bound for the degree of the determinant of W)
13
returns the determinant of a real polynomial matrix (computation made by
16
k is an integer larger than the actual degree of the determinant of W.
18
The default value of k is the smallest power of 2 which is larger than
21
Method: evaluate the determinant of W for the Fourier frequencies and
22
apply inverse FFT to the coefficients of the determinant.
