Function/Subroutine Documentation

subroutine dlasdt (integer N, integer LVL, integer ND, integer, dimension( * ) INODE, integer, dimension( * ) NDIML, integer, dimension( * ) NDIMR, integer MSUB)

DLASDT creates a tree of subproblems for bidiagonal divide and conquer. Used by sbdsdc.

Purpose:


DLASDT creates a tree of subproblems for bidiagonal divide and
conquer.

Parameters:

N


N is INTEGER
On entry, the number of diagonal elements of the
bidiagonal matrix.

LVL


LVL is INTEGER
On exit, the number of levels on the computation tree.

ND


ND is INTEGER
On exit, the number of nodes on the tree.

INODE


INODE is INTEGER array, dimension ( N )
On exit, centers of subproblems.

NDIML


NDIML is INTEGER array, dimension ( N )
On exit, row dimensions of left children.

NDIMR


NDIMR is INTEGER array, dimension ( N )
On exit, row dimensions of right children.

MSUB


MSUB is INTEGER
On entry, the maximum row dimension each subproblem at the
bottom of the tree can be of.
