28 * Exception to be thrown when a symmetric, definite positive
29 * {@link org.hipparchus.linear.RealLinearOperator} is expected.
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.

36 * @deprecated as of 1.0, this exception is replaced by {@link MathIllegalArgumentException}
