Solving partial differential equations using the NAG Library

چکیده
A partial differential equation (PDE) is a mathematical relation which involves functions of multiple variables and their partial derivatives. PDEs are used to formulate (and hence to aid in the solution of) problems involving functions of several variables, and they arise in a variety of important fields. For example, in physics, they are used to describe the propagation of sound or heat, electrostatics, electrodynamics, fluid flow and elasticity, whilst in finance, they have been used in the modelling of the pricing of financial options. Accordingly, the study of their properties and methods of solution has received a great deal of attention [1].
