Teuchos::RCP< Epetra_Operator > createTridiagEpetraLinearOp (const int globalDim, const double diagScale, const bool verbose, std::ostream &out)
 This function generates a tridiagonal linear operator using Epetra.

Function Documentation

Teuchos::RCP<Epetra_Operator> createTridiagEpetraLinearOp ( const int  globalDim,
const double  diagScale,
const bool  verbose,
std::ostream &  out 
)

This function generates a tridiagonal linear operator using Epetra.

Specifically, this function returns a smart pointer to the matrix:

\[ A= \left[\begin{array}{rrrrrrrrrr} 2 a & -1 \\ -1 & 2 a & -1 \\ & \ddots & \ddots & \ddots \\ & & -1 & 2 a & -1 \\ & & & -1 & 2 a \end{array}\right] \]

where diagScale is $a$ and globalDim is the glboal dimension of the matrix.
