public class NonPositiveDefiniteOperatorException
- extends MathIllegalArgumentException
Exception to be thrown when a symmetric, definite positive
RealLinearOperator
is expected.
Since the coefficients of the matrix are not accessible, the most
general definition is used to check that A
is not positive
definite, i.e. there exists x
such that x' A x <= 0
.
In the terminology of this exception, A
is the "offending"
linear operator and x
the "offending" vector.
