org.netlib.arpack.Dnconv
public class Dnconv
- 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: dnconv
\Description:
Convergence testing for the nonsymmetric Arnoldi eigenvalue routine.
\Usage:
call dnconv
( N, RITZR, RITZI, BOUNDS, TOL, NCONV )
\Arguments
N Integer. (INPUT)
Number of Ritz values to check for convergence.
RITZR, Double precision arrays of length N. (INPUT)
RITZI Real and imaginary parts of the Ritz values to be checked
for convergence.
BOUNDS Double precision array of length N. (INPUT)
Ritz estimates for the Ritz values in RITZR and RITZI.
TOL Double precision scalar. (INPUT)
Desired backward error for a Ritz value to be considered
"converged".
NCONV Integer scalar. (OUTPUT)
Number of "converged" Ritz values.
