Methods

CCSMatrix.__init__(*args, **kwargs)
CCSMatrix.clear_rhs(self, ...)	Zero all elements in the rhs vector corresponding to rhs_index.
CCSMatrix.construct(self, ...)	Constructing the matrix involves taking the metadata submatrix positions throughout the matrix and allocating the memory and building the various CCS matrix structures.
CCSMatrix.declare_equations(self, ...[, ...])	This defines generally what equations exist in the matrix.
CCSMatrix.declare_subdiagonal_view(self, ...)
CCSMatrix.declare_submatrix_view(self, ...)
CCSMatrix.factor(self)	Factors the matrix.
CCSMatrix.get_matrix_elements(self)	Returns the sparse CCS format for the current state of this matrix.
CCSMatrix.get_rhs_view(self, unsigned int index)	Returns a view of the rhs vector corresponding to index.
CCSMatrix.print_matrix(self)	Print a view of the non-zero elements in this matrix.
CCSMatrix.print_rhs(self, ...)	Print a view of the rhs vector corresponding to rhs_index.
CCSMatrix.refactor(self)	Refactors the matrix.
CCSMatrix.set_rhs(self, ...)	Sets the value of the entry at position index of the rhs_index`th right-hand-side vector to `value.
CCSMatrix.solve(self, int transpose=False, ...)	Solves the matrix equation.
CCSMatrix.solve_extra_rhs(self, ...)	Solves the matrix equation for extra right-hand sides.
CCSMatrix.to_scipy_coo(self)	Converts the current matrix to a scipy COO (Coordinate) sparse matrix.
CCSMatrix.to_scipy_csc(self)	Converts the current matrix to a scipy CSC (Compressed Sparse Column) sparse matrix.
CCSMatrix.to_scipy_csr(self)	Converts the current matrix to a scipy CSR (Compressed Sparse Row) sparse matrix.
