Getting started with MATLAB PDE Toolbox

To get started, launch MATLAB by double-clicking the icon on the desktop. Once there, you can

type "pdetool" at the prompt. In a few seconds, MATLAB will open up a graphical user-interface

(GUI) for you to work in. You will notice that there is an empty grid in front of you. If you want

to change any characteristics of the grid (such as the minimum or maximum values, increments,

the number of gridlines, or the “snap” characteristics of the drawing tools) go to the Options

heading on the toolbox menu. To set the PDE toolbox to work with parameters for heat transfer

problems change the pull-down menu in the toolbar menu from “Generic Scalar” to “Heat

Transfer.” Notice that there are a variety of other problems that you can solve.

Geometry

To define the geometry on which you want to solve your PDE, go to the Draw menu. There are

some simple shapes to choose from such as circles and squares. Making shapes on the grid

should be similar to many other drawing programs you have used previously. For more precise

drawings you can use the “snap” characteristics or double-click on an object after it has been

drawn to set its dimensions in the pop-up window.

For more complex geometries you can add and subtract simple geometric shapes. For example,

set this to
