Class Dsconv

java.lang.Object
  extended by org.netlib.arpack.Dsconv

public class Dsconv
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.

*----------------------------------------------------------------------- \BeginDoc \Name: dsconv \Description: Convergence testing for the symmetric Arnoldi eigenvalue routine. \Usage: call dsconv ( N, RITZ, BOUNDS, TOL, NCONV ) \Arguments N Integer. (INPUT) Number of Ritz values to check for convergence. RITZ Double precision array of length N. (INPUT) The Ritz values to be checked for convergence. BOUNDS Double precision array of length N. (INPUT) Ritz estimates associated with the Ritz values in RITZ. TOL Double precision scalar. (INPUT) Desired relative accuracy for a Ritz value to be considered "converged". NCONV Integer scalar. (OUTPUT) Number of "converged" Ritz values. \EndDoc ----------------------------------------------------------------------- \BeginLib \Routines called: second ARPACK utility routine for timing. dlamch LAPACK routine that determines machine constants. \Author Danny Sorensen Phuong Vu Richard Lehoucq CRPC / Rice University Dept. of Computational & Houston, Texas Applied Mathematics Rice University Houston, Texas \SCCS Information: @(#) FILE: sconv.F SID: 2.4 DATE OF SID: 4/19/96 RELEASE: 2 \Remarks 1. Starting with version 2.4, this routine no longer uses the Parlett strategy using the gap conditions. \EndLib -----------------------------------------------------------------------
