linalg.direct_solvers

Classes

BandedSolver(u, l, bmat[, transposed])	Solve the equation Ax = b for x, assuming A is banded matrix.
SparseSolver(spmat[, transposed])	Solve the equation Ax = b for x, assuming A is scipy sparse matrix.

Details

class BandedSolver(u, l, bmat, transposed=False)

Bases: LinearSolver

Solve the equation Ax = b for x, assuming A is banded matrix.

Parameters:

uinteger

Number of non-zero upper diagonal.

linteger

Number of non-zero lower diagonal.

bmatnd-array

Banded matrix.

property finfo

property sinfo

property space

transpose()

Return the transpose of the LinearSolver.

solve(rhs, out=None)

Solves for the given right-hand side.

Parameters:

rhsndarray

The right-hand sides to solve for. The vectors are assumed to be given in C-contiguous order, i.e. if multiple right-hand sides are given, then rhs is a two-dimensional array with the 0-th index denoting the number of the right-hand side, and the 1-st index denoting the element inside a right-hand side.

outndarray | NoneType

Output vector. If given, it has to have the same shape and datatype as rhs.

class SparseSolver(spmat, transposed=False)

Bases: LinearSolver

Solve the equation Ax = b for x, assuming A is scipy sparse matrix.

Parameters:

spmatscipy.sparse.spmatrix

Generic sparse matrix.

property space

transpose()

Return the transpose of the LinearSolver.

solve(rhs, out=None)

Solves for the given right-hand side.

Parameters:

rhsndarray

The right-hand sides to solve for. The vectors are assumed to be given in C-contiguous order, i.e. if multiple right-hand sides are given, then rhs is a two-dimensional array with the 0-th index denoting the number of the right-hand side, and the 1-st index denoting the element inside a right-hand side.

outndarray | NoneType

Output vector. If given, it has to have the same shape and datatype as rhs.
