implements Solver
Conjugate Gradient Solver.


Variable Index

o alphaTol

o nReset
o res
o rtrNew
o secantSigma

Constructor Index

o CGNonlinSolver2()
o CGNonlinSolver2(Iterator)

Method Index

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