qmr(A, b, x0=None, tol=1.0000000000000001e-05, maxiter=None, xtype=None, M1=None, M2=None, callback=None)
Use Quasi-Minimal Residual iteration to solve A x = b

Parameters
A : {sparse matrix, dense matrix, LinearOperator}
LinearOperator
The N-by-N matrix of the linear system.
b : {array, matrix}
Right hand side of the linear system. Has shape (N,) or (N,1).
splu(A, permc_spec=2, diag_pivot_thresh=1.0, drop_tol=0.0, relax=1, panel_size=10)
A linear solver, for a sparse, square matrix A, using LU decomposition where L is a lower triangular matrix and
U is an upper triagular matrix.
Returns a factored_lu object. (scipy.sparse.linalg.dsolve._superlu.SciPyLUType)
See scipy.sparse.linalg.dsolve._superlu.dgstrf for more info.
spsolve(A, b, permc_spec=2)
Solve the sparse linear system Ax=b
test
Run tests for module using nose.
Parameters
label : {‘fast’, ‘full’, ‘’, attribute identifier}, optional
Identifies the tests to run. This can be a string to pass to the nosetests executable
with the ‘-A’ option, or one of several special values. Special values are:
‘fast’ - the default - which corresponds to the nosetests -A
option of ‘not slow’.
‘full’ - fast (as above) and slow tests as in the
‘no -A’ option to nosetests - this is the same as ‘’.
None or ‘’ - run all tests. attribute_identifier - string passed directly to nosetests as
‘-A’.
verbose : int, optional
Verbosity value for test outputs, in the range 1-10. Default is 1.
