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.
