Synopsis
#include <flint/gr_mat.h>int gr_mat_jordan_blocks(gr_vec_t lambda, slong * num_blocks, slong * block_lambda, slong * block_size, const gr_mat_t A, gr_ctx_t ctx)sourceComputes the Jordan block structure of a square matrix over a field containing its eigenvalues: the distinct eigenvalues in lambda, the number of blocks in num_blocks, and for each block the index of its eigenvalue in block_lambda and its size in block_size (arrays of length at least n). The block sizes are determined from the ranks of the powers of A - \lambda I.
