LIBSNAP
About LIBSNAP
LIBSNAP is a library for numericsymbolic computations (e.g. approximate polynomial GCD, approximate factorization and so on) by C language. Our aim is 1) to make numericsymbolic computations easy to use, and 2) to compare several algorithms on the same framework. The license is a BSD 2Clause license.
However, the current version only includes very basic functions for univariate polynomials. Others including higher level functions will be implemented later.
