[.]). In most of cases namely such conforming triangulations are used in the finite element modelling and analysis.

Algebraic differential equations,ve definite system matrix, are instances of . on a finite dimensional subspace. In the finite element method, the problem under approximation is infinite dimensional, whereas in the conjugate gradient method it is finite, though usually high dimensional. We will briefly recall both methods, and then

This method can be considered as direct as well as iterative. It is similar to the Lanczos method for fin

Some models involve both time and space as independent parameters and therefore it is necessary to solve such a linear system efficiently at all time-steps.
