4.2.2.2. pde.grids.operators.common module¶
Common functions that are used by many operators
- make_general_poisson_solver(matrix, vector, method: str = 'auto') Callable[[numpy.ndarray, numpy.ndarray], None][source]¶
make an operator that solves Poisson’s problem
- Parameters
matrix – The (sparse) matrix representing the laplace operator on the given grid.
vector – The constant part representing the boundary conditions of the Laplace operator.
method (str) – The chosen method for implementing the operator
- Returns
A function that can be applied to an array of values to obtain the solution to Poisson’s equation where the array is used as the right hand side
- make_laplace_from_matrix(matrix, vector) Callable[[numpy.ndarray, numpy.ndarray], None][source]¶
make a Laplace operator using matrix vector products
- Parameters
matrix – The (sparse) matrix representing the laplace operator on the given grid.
vector – The constant part representing the boundary conditions of the Laplace operator.
- Returns
A function that can be applied to an array of values to obtain the solution to Poisson’s equation where the array is used as the right hand side
