When have an equation which relations multivariable functions and their partial derivates, we have a partial differential euqations.
Partial differential equations are using in a lot of phenomenas such as sound, heat, diffusion, electrostatics, electrodynamics, fluid dynamics, quantum mechanics, etc.
In case of second-order partial differential equations, we can classified them as parabolic, hyperbolic and elliptic.
The codes in python can be found in Numerical-Analysis 7th ed. Richard L. Burden and codes in matlab can be found in Numerical-Analysis 2nd ed. Timothy Sauer.
This repository is used to solve partial differential equations by finite element method or finite difference method.
