public class SteepDescentSlv
extends IterativeSlv
implements LinearSolver
Steepest Descent Solver.


By decomposing the calculations into several routines, CGSolver is made to be subclassed, so that slight modifications to the standard behavior can be made.

Variable Index

o res
o reset
o rtr

Constructor Index

o SteepDescentSlv()
o SteepDescentSlv(Iterator)

Method Index

o doOneStep(Vector)
o getNormResidual()
o getResidual()
o setReset(int)
after each reset-th iteration I compute the exact residual to remove accumulated floating point error (default is 50).
o solve(Operator, Vector, Vector)
Solves Ax = b for x
"Solve" is used in a loose sense.

Variables

o res 
 protected Vector res
o rtr 
 protected float rtr
o reset 
 protected int reset

Constructors

o SteepDescentSlv 
 public SteepDescentSlv()
o SteepDescentSlv 
 public SteepDescentSlv(Iterator iterator)

Methods

o setReset 
 public void setReset(int reset)
after each reset-th iteration I compute the exact residual to remove accumulated floating point error (default is 50).

o getResidual 
 public Vector getResidual()
Overrides:
getResidual in class IterativeSlv
o getNormResidual 
 public float getNormResidual()
Overrides:
getNormResidual in class IterativeSlv
o solve 
 public void solve(Operator A,
                   Vector b,
                   Vector x)
Solves Ax = b for x
"Solve" is used in a loose sense.

Overrides:
solve in class IterativeSlv
o doOneStep 
 protected void doOneStep(Vector v)
