28 * Exception to be thrown when a self-adjoint {@link org.hipparchus.linear.RealLinearOperator}
29 * is expected.
30 * Since the coefficients of the matrix are not accessible, the most
31 * general definition is used to check that A is not self-adjoint, i.e.
32 * there exist x and y such as {@code | x' A y - y' A x | >= eps},
33 * where {@code eps} is a user-specified tolerance, and {@code x'}
34 * denotes the transpose of {@code x}.
35 * In the terminology of this exception, {@code A} is the "offending"
36 * linear operator, {@code x} and {@code y} are the first and second
37 * "offending" vectors, respectively.
38 *
39 * @deprecated as of 1.0, this exception is replaced by {@link MathIllegalArgumentException}
