Sparse arrays (dpnp.scipy.sparse)

Hint

SciPy API Reference: Sparse arrays (scipy.sparse)

Sparse matrix classes

csr_matrix

Compressed Sparse Row matrix on a SYCL device.

Identifying sparse matrices

issparse

Determine whether x is a dpnp sparse matrix type.

Sparse linear algebra (dpnp.scipy.sparse.linalg)

Hint

SciPy API Reference: Sparse linear algebra (scipy.sparse.linalg)

Abstract linear operators

LinearOperator	Common interface for performing matrix-vector products, backed by dpnp arrays.
aslinearoperator	Return A as a LinearOperator.

Iterative solvers for linear systems

cg	Use Conjugate Gradient iteration to solve Ax = b for a Hermitian positive-definite A.
gmres	Use Generalized Minimal RESidual iteration to solve Ax = b.
minres	Use MINimum RESidual iteration to solve Ax = b.
