 * Exception to be thrown when a symmetric, definite positive
 * {@link RealLinearOperator} is expected.
 * Since the coefficients of the matrix are not accessible, the most
 * general definition is used to check that {@code A} is not positive
 * definite, i.e.  there exists {@code x} such that {@code x' A x <= 0}.
 * In the terminology of this exception, {@code A} is the "offending"
 * linear operator and {@code x} the "offending" vector.
 * @since 3.0
