Corona688,

Thank you! That has been a great help to getting the start that I needed. I had worked with splitting the original array, but then had my loops becoming way too complicated and then they weren't running correctly.

slarra

slarra.f(3)							      LAPACK							       slarra.f(3)

NAME

       slarra.f -

SYNOPSIS

   Functions/Subroutines
       subroutine slarra (N, D, E, E2, SPLTOL, TNRM, NSPLIT, ISPLIT, INFO)
	   SLARRA computes the splitting points with the specified threshold.

Function/Subroutine Documentation
   subroutine slarra (integerN, real, dimension( * )D, real, dimension( * )E, real, dimension( * )E2, realSPLTOL, realTNRM, integerNSPLIT,
       integer, dimension( * )ISPLIT, integerINFO)
       SLARRA computes the splitting points with the specified threshold.

       Purpose:

	    Compute the splitting points with threshold SPLTOL.
	    SLARRA sets any "small" off-diagonal elements to zero.

       Parameters:
	   N

		     N is INTEGER
		     The order of the matrix. N > 0.

	   D

		     D is REAL array, dimension (N)
		     On entry, the N diagonal elements of the tridiagonal
		     matrix T.

	   E

		     E is REAL array, dimension (N)
		     On entry, the first (N-1) entries contain the subdiagonal
		     elements of the tridiagonal matrix T; E(N) need not be set.
		     On exit, the entries E( ISPLIT( I ) ), 1 <= I <= NSPLIT,
		     are set to zero, the other entries of E are untouched.

	   E2

		     E2 is REAL array, dimension (N)
		     On entry, the first (N-1) entries contain the SQUARES of the
		     subdiagonal elements of the tridiagonal matrix T;
		     E2(N) need not be set.
		     On exit, the entries E2( ISPLIT( I ) ),
		     1 <= I <= NSPLIT, have been set to zero

	   SPLTOL

		     SPLTOL is REAL
		     The threshold for splitting. Two criteria can be used:
		     SPLTOL<0 : criterion based on absolute off-diagonal value
		     SPLTOL>0 : criterion that preserves relative accuracy

	   TNRM

		     TNRM is REAL
		     The norm of the matrix.

	   NSPLIT

		     NSPLIT is INTEGER
		     The number of blocks T splits into. 1 <= NSPLIT <= N.

	   ISPLIT

		     ISPLIT is INTEGER array, dimension (N)
		     The splitting points, at which T breaks up into blocks.
		     The first block consists of rows/columns 1 to ISPLIT(1),
		     the second of rows/columns ISPLIT(1)+1 through ISPLIT(2),
		     etc., and the NSPLIT-th consists of rows/columns
		     ISPLIT(NSPLIT-1)+1 through ISPLIT(NSPLIT)=N.

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
