Enum Class Diag

java.lang.Enum<Diag>

smile.math.blas.Diag

All Implemented Interfaces:

Serializable, Comparable<Diag>, Constable

public enum Diag
extends 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.
