fq_zech_mat_similarity
Synopsis
#include <flint/fq_zech_mat.h>void fq_zech_mat_similarity(fq_zech_mat_t A, slong r, fq_zech_t d, const fq_zech_ctx_t ctx)Replaces the square matrix A by P^{-1} A P, where P is the identity matrix with the entries in row r and every column j \notin \{r - 1, r\} replaced by d. Such transforms preserve the characteristic and minimal polynomials.
