Enum Constant Detail

DOOLITTLE

public static final LU.Method DOOLITTLE

use the Doolittle algorithm

This throws a Singularity exception when applied to a singular matrix.

GAUSSIAN_ELIMINATION

public static final LU.Method GAUSSIAN_ELIMINATION

use Gaussian Elimination method

This never throws an exception.

Method Detail

values

public static LU.Method[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LU.Method c : LU.Method.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LU.Method valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
