Method Detail

testNonSquareOperator

public void testNonSquareOperator()

testDimensionMismatchRightHandSide

public void testDimensionMismatchRightHandSide()

testDimensionMismatchSolution

public void testDimensionMismatchSolution()

testNonPositiveDefiniteLinearOperator

public void testNonPositiveDefiniteLinearOperator()

testUnpreconditionedSolution

public void testUnpreconditionedSolution()

testUnpreconditionedInPlaceSolutionWithInitialGuess

public void testUnpreconditionedInPlaceSolutionWithInitialGuess()

testUnpreconditionedSolutionWithInitialGuess

public void testUnpreconditionedSolutionWithInitialGuess()

testUnpreconditionedResidual

public void testUnpreconditionedResidual()

Check whether the estimate of the (updated) residual corresponds to the exact residual. This fails to be true for a large number of iterations, due to the loss of orthogonality of the successive search directions. Therefore, in the present test, the number of iterations is limited.
