maspack.solvers.DirectSolverTestBase

Direct Known Subclasses:

AccelerateSolverTest, MumpsSolverTest, PardisoSolverTest

public abstract class DirectSolverTestBase
extends UnitTest

Base class for testing DirectSolver implementations. It provides the tests which are common to all such solvers; subclasses supply the solver itself, through createSolver(), along with any solver specific tests.

Tests which depend on optional functionality are guarded by the corresponding capability queries (DirectSolver.hasMultipleRhsSolves() and DirectSolver.hasIterativeSolves()), while the few expectations which legitimately differ between solvers are supplied by overridable methods such as expectedNumNegEigenvaluesSPD().

Method Summary

Modifier and Type	Method and Description
void	test()
void	testBasics() Runs all the solver independent tests.
void	testCRSInterface() Tests the analyze/factor/solve sequence using the CRS interface, which is the one used by KKTSolver and MurtyMechSolver.
void	testInertia() Tests the inertia reported for a symmetric indefinite matrix.
void	testIterativeSettings() Tests the iterative solve settings, if the solver supports iterative solves.
void	testLargeMatrix() Tests the solver on a larger matrix, read from testMatrix.mat.
void	testSingularMatrix() Tests that a singular matrix is detected and reported through the perturbed pivot count, rather than causing the factorization to fail.
void	testSPD() Tests an SPD matrix, for which solvers normally use a Cholesky factorization.
void	testStateAndReuse() Tests state handling and reuse of the solver after a call to dispose().
void	testSymmetric() Tests the analyze/factor/solve sequence for a symmetric indefinite matrix supplied as a Matrix object.
void	testUnsymmetric() Tests an unsymmetric matrix: M = [1 2 3 0 4 0 5 0 6]

Method Detail

testSymmetric

public void testSymmetric()

Tests the analyze/factor/solve sequence for a symmetric indefinite matrix supplied as a Matrix object.

testInertia

public void testInertia()

Tests the inertia reported for a symmetric indefinite matrix.

testCRSInterface

public void testCRSInterface()

Tests the analyze/factor/solve sequence using the CRS interface, which is the one used by KKTSolver and MurtyMechSolver.

testUnsymmetric

public void testUnsymmetric()

Tests an unsymmetric matrix: M = [1 2 3 0 4 0 5 0 6]

testSPD

public void testSPD()

Tests an SPD matrix, for which solvers normally use a Cholesky factorization.

testSingularMatrix

public void testSingularMatrix()

Tests that a singular matrix is detected and reported through the perturbed pivot count, rather than causing the factorization to fail.

testStateAndReuse

public void testStateAndReuse()

Tests state handling and reuse of the solver after a call to dispose().

testLargeMatrix

public void testLargeMatrix()
                     throws java.io.IOException

Tests the solver on a larger matrix, read from testMatrix.mat.

Throws:

java.io.IOException

testIterativeSettings

public void testIterativeSettings()

Tests the iterative solve settings, if the solver supports iterative solves.

testBasics

public void testBasics()
