Enum Constant Detail

QR

public static final Kernel.Method QR

use QR decomposition; moderately expensive (recommended)

GAUSSIAN_JORDAN_ELIMINATION

public static final Kernel.Method GAUSSIAN_JORDAN_ELIMINATION

use Gauss-Jordan elimination; cheap but subject to numerical stability (rounding errors)

Method Detail

values

public static Kernel.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 (Kernel.Method c : Kernel.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 Kernel.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
