Enum Constant Details

LA

public static final ARPACK.SymmOption LA

The largest algebraic eigenvalues.

SA

public static final ARPACK.SymmOption SA

The smallest algebraic eigenvalues.

LM

public static final ARPACK.SymmOption LM

The eigenvalues largest in magnitude.

SM

public static final ARPACK.SymmOption SM

The eigenvalues smallest in magnitude.

BE

public static final ARPACK.SymmOption BE

Computes nev eigenvalues, half from each end of the spectrum. When nev is odd, computes one more from the high end than from the low end.

Method Details

values

public static ARPACK.SymmOption[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ARPACK.SymmOption valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
