Hi FOAMERS

I am trying to access to elements of the coefficient matrix of an equation using lduAddresing

Foloowing the procedure in "OpenFOAM guide/Matrices in OpenFOAM" http://openfoamwiki.net/index.php/Matrices_in_OpenFOAM

I use

scalarField *lowerPtr_;
scalarField *diagPtr_;
scalarField *upperPtr_;

for (register label face=0; face<l.size(); face++)
{
Diag[l[face]] -= Lower[face];
Diag[u[face]] -= Upper[face];
}

But I get the following errors

error: ‘l’ was not declared in this scope
error: ‘Diag’ was not declared in this scope
error: ‘Lower’ was not declared in this scope
error: ‘u’ was not declared in this scope
error: ‘Upper’ was not declared in this scope

Do you have any idea what these errors are?
PS: I have included these header files

#include "fvCFD.H"
#include "wallFvPatch.H"
#include <fstream>
#include <string>
#include <stdio.h>
#include <time.h>
#include <iostream>
