Detailed Description

Defines all functions required by Solver class to allocate, assemble and solve a linear system of equation.

Linear system is defined as A*x=B, where A is a square matrix and F is a vector. Member functions are provided to access a specific element within A and B. Objects of derived classes should make appropriate calls to the numeric library in implementation of virtual functions to assemble and solve the linear system.

See comments for each virtual member for more information about how to derive a new LinearSystemWrapper class. An example derived class LinearSystemWrapperVNL is defined to use VNL sparse matrix representation and solver.
