DREORT(3)

SYNOPSIS
SUBROUTINE DREORT (NCOMP, Y, YP, YHP, NIV, W, S, P, IP, STOWA, + IFLAG)

NAME
dreort - Subsidiary to DBVSUP

LIBRARY
SLATEC

TYPE
DOUBLE PRECISION (REORT-S, DREORT-D)

AUTHOR
Watts, H. A., (SNLA)

DESCRIPTION
********************************************************************** INPUT ********* Y, YP and YHP = homogeneous solution matrix and particular solution vector to be orthonormalized. IFLAG = 1 -- store YHP into Y and YP, test for reorthonormalization, orthonormalize if needed, save restart data. 2 -- store YHP into Y and YP, reorthonormalization, no restarts. (preset orthonormalization mode) 3 -- store YHP into Y and YP, reorthonormalization (when INHOMO=3 and X=XEND). ********************************************************************** OUTPUT ********* Y, YP = orthonormalized solutions. NIV = number of independent vectors returned from DMGSBV. IFLAG = 0 -- reorthonormalization was performed. 10 -- solution process must be restarted at the last orthonormalization point. 30 -- solutions are linearly dependent, problem must be restarted from the beginning. W, P, IP = orthonormalization information. **********************************************************************
