Partial Differential Equations This article describes two Python modules for solving partial differential equations (PDEs): PyCC is designed as a Matlab-like environment for writing algorithms for solving PDEs, and SyFi creates matrices based on symbolic mathematics, code generation, and the ﬁnite element method.
- model = createpde(N) returns a PDE model object for a system of N equations. A complete PDE model object contains a description of the problem you want to solve, including the geometry, mesh, and boundary conditions.
example pdemesh (p,e,t,u) plots PDE node or triangle data u using a mesh plot. The function plots the node data if u is a column vector, and triangle data if u is a row vector. If you want to have more control over your mesh plot, use pdeplot or pdeplot3D instead of pdemesh.
- specifyCoefficients(model,Name,Value) defines the specified coefficients in each Name to each associated Value, and includes them in model.You must specify all of these names: m, d, c, a, and f.This syntax applies coefficients to the entire geometry.
This example shows how to solve a transistor partial differential equation (PDE) and use the results to obtain partial derivatives that are part of solving a larger problem. Solve System of PDEs. This example shows how to formulate, compute, and plot the solution to a system of two partial differential equations.
- MATLAB codes. The code for solving perturbed mKdV: mkdvB.m. This is a simple adaptation of Nick Trefethen’s code for solving the KdV equation, p27.m. It solves on [-π,π] with periodic boundary conditions. mkdvB.m is used as follows:

- The partial differential equation. u t = a 2 u xx. is used to model one-dimensional temperature evolution. We will not discuss the derivation of this equation here. The most important features of this equation are the second spatial derivative u xx and the first derivative with respect to time, u t.
This is a slide-based introduction to techniques for solving parabolic partial differential equations in Matlab. It comes from a course I teach as part of an...
- There are lots of MATLAB scripts for solving 1D wave equation already out there on the internet, for example, this. Also, MATLAB has a PDE tool box that could handle wave equation, you could launch the GUI of PDE tool box from the start menu of MATLAB, for a step-by-step instruction please see the link above.
Partial Differential Equation Toolbox lets you import 2D and 3D geometries from STL or mesh data. You can automatically generate meshes with triangular and tetrahedral elements. You can solve PDEs by using the finite element method, and postprocess results to explore and analyze them.
