-
These functions set thresholds in the selection of an algorithm from N^2,
Karatsuba, FFT algorithms for univariate polynomial multiplication.
-
Products of univariate polynomials are computed by N^2, Karatsuba,
FFT algorithms. The algorithm selection is done according to the degrees of
input polynomials and the thresholds.
-
See the description of each function for details.
