4.1.5.1.2 pde.backends.scipy.operators.common module
Common functions that are used by many operators.
- make_general_poisson_solver(matrix, vector, method='auto')[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
- Return type:
OperatorImplType
- make_laplace_from_matrix(matrix, vector)[source]
Make a Laplace operator using matrix vector products.
- Parameters:
matrix – (Sparse) matrix representing the laplace operator on the given grid
vector – 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 result of applying the linear operator matrix and the offset given by vector.
- Return type:
Callable[[NumericArray, NumericArray | None], NumericArray]
