Class Ssconv
java.lang.Object
org.netlib.arpack.Ssconv
public class Ssconv
- 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.

\Name: ssconv
\Description:
Convergence testing for the symmetric Arnoldi eigenvalue routine.
\Usage:
call ssconv
( N, RITZ, BOUNDS, TOL, NCONV )
\Arguments
N Integer. (INPUT)
Number of Ritz values to check for convergence.
RITZ Real array of length N. (INPUT)
The Ritz values to be checked for convergence.
BOUNDS Real array of length N. (INPUT)
Ritz estimates associated with the Ritz values in RITZ.
TOL Real scalar. (INPUT)
Desired relative accuracy for a Ritz value to be considered
"converged".
NCONV Integer scalar. (OUTPUT)
Number of "converged" Ritz values.
