Web26 jun. 2010 · 1 I cant seem to find any info on, which algorithms in the NTL C++ libraries are used. I am especially interested in the algorithms used for: Modular square root (SqrRootMod) Kernel of matrix over GF (2) (kernel for mat_GF2 objects) Greatest common divisor (GCD - this is probably euclids algorithm) Modular inverse (InvMod) Jacobi … WebTo obtain the source code and documentation for NTL, download ntl-xxx.tar.gz from Download NTL library, placing it in a different directory. Run the configuration script. Working in the directory where you placed the NTL library, do the following (here, “xxx” denotes the desired version number of NTL; any version of NTL can be employed):

Web我正在使用 NTL 库试验伽罗华域。 GF2 是整数 mod 2, GF2X 是 GF2 上的多项式, GF2E 是 GF2E 上的环/场扩展 GF2. 我面临的问题是我按如下方式初始化不可约多项式 GF2X … Web{ mat_GF2 x; transpose(x, a); NTL_OPT_RETURN(mat_GF2, x); } void clear(mat_GF2& a); // x = 0 (dimension unchanged) long IsZero(const mat_GF2& a); // test if a is the zero … restore renew
