acb_siegel_reduce
Synopsis
#include <flint/acb_theta.h>void acb_siegel_reduce(fmpz_mat_t mat, const acb_mat_t tau, slong prec)sourceSets mat to a symplectic matrix such that is as reduced as possible, by repeatedly reducing with LLL (block-diagonal matrices), the real part of (trigonal matrices), and applying fundamental matrices that increase . If the entries of are not of reasonable size or is vanishingly small, mat is set to the identity.
