Enum Constant Detail

One

public static final Matrix.Norm One

Maximum absolute row sum

Frobenius

public static final Matrix.Norm Frobenius

The root of sum of the sum of squares

Infinity

public static final Matrix.Norm Infinity

Maximum column sum

Maxvalue

public static final Matrix.Norm Maxvalue

Largest entry in absolute value. Not a proper matrix norm

Method Detail

values

public static Matrix.Norm[] 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 (Matrix.Norm c : Matrix.Norm.values())
    System.out.println(c);

Returns:

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

valueOf

public static Matrix.Norm valueOf(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:

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

NullPointerException - if the argument is null

netlib

public String netlib()

Returns:

the String as required by the netlib libraries to represent this norm.
