28   * Exception to be thrown when a symmetric, definite positive

30   * Since the coefficients of the matrix are not accessible, the most
31   * general definition is used to check that {@code A} is not positive
32   * definite, i.e.  there exists {@code x} such that {@code x' A x <= 0}.
33   * In the terminology of this exception, {@code A} is the "offending"
34   * linear operator and {@code x} the "offending" vector.
