function

`scipy.sparse.linalg._isolve.utils:make_system`

source: /scipy/sparse/linalg/_isolve/utils.py :31

Signature

def make_system ( A , M , x0 , b )

Summary

Make a linear system Ax=b

Parameters

A : LinearOperator: sparse or dense matrix (or any valid input to aslinearoperator)
M : {LinearOperator, Nones}: preconditioner sparse or dense matrix (or any valid input to aslinearoperator)
x0 : {array_like, str, None}: initial guess to iterative method. x0 = 'Mb' means using the nonzero initial guess M @ b. Default is None, which means using the zero initial guess.
b : array_like: right hand side

Returns

: (A, M, x, b)

A: A
M: M
x: x
b: b
