Function/Subroutine Documentation

subroutine dlasdt (integerN, integerLVL, integerND, integer, dimension( * )INODE, integer, dimension( * )NDIML, integer, dimension( * )NDIMR, integerMSUB)

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.
