Limitations
The Galois field, GF(2m), over which this function works must have 256 or fewer elements. In other words, m must be an integer in the range [1, 8].
Algorithms
If x
is a column vector, fft
applies dftmtx
to the primitive element of the Galois field and multiplies the
resulting matrix by x
. If x
is a row vector,
the order of the matrix multiplication is reversed.
