- class Matrix_rational_sparse
-
The Matrix_rational_sparse class derives from
Matrix, and defines functionality for sparse matrices
over the field
of rational numbers.
Matrix_rational_sparse( |
parent, [entries=True], [coerce_entries=True], [copy=0]) |
-
Instances of class Matrix_rational_sparse have the following methods (in addition to inherited methods and special methods):
charpoly,
echelon_form,
hessenberg_form,
pivots
These methods are defined as follows:
-
Return the characteristic polynomial of this matrix.
echelon_form( |
[height_guess=None]) |
-
-
Return the Hessenberg form of this sparse matrix.
