Enum Diag

java.lang.Object

java.lang.Enum<Diag>

smile.math.blas.Diag

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Diag>

public enum Diag
extends java.lang.Enum<Diag>

The flag if a triangular matrix has unit diagonal elements. Some LAPACK routines have an option to handle unit triangular matrices (that is, triangular matrices with diagonal elements = 1). If the matrix is unit triangular, the diagonal elements of the matrix need not be stored, and the corresponding array elements are not referenced by the LAPACK routines. The storage scheme for the rest of the matrix (whether conventional, packed or band) remains unchanged.

Enum Constant Detail

NON_UNIT

public static final Diag NON_UNIT

Non-unit triangular.

UNIT

public static final Diag UNIT

Unit triangular.

Method Detail

values

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

Returns:

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

valueOf

public static Diag 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

blas

public int blas()

Returns the byte value for BLAS.

lapack

public byte lapack()

Returns the byte value for LAPACK.
