Berkeley Madonna is a program that numerically solves systems of ordinary differential equations (ODEs) and difference equations. It was originally developed to execute models written in STELLA® more quickly. Over time, we added our own unique features which have made Berkeley Madonna into a fast, self-contained, and easy-to-use modeling tool. Berkeley Madonna is available for both Macintosh and Windows platforms. While these versions are mostly identical, there are some differences which are noted throughout this guide with the notation [Macintosh] or [Windows].

System Requirements
Macintosh: Power Macintosh or compatible computer
1 with a PowerPC processor and least two megabytes of free memory. It may require more memory depending on the size of your models and the amount of data they generate. The flowchart editor requires MRJ 2.1 or later to be installed on your system.
2 You can download the latest version of MRJ from http://www.apple.com/java. Note that Mac OS 9 comes with MRJ 2.1.4. We recommend that you use MRJ 2.2 or later since it offers significantly improved performance over MRJ 2.1.x. Windows: PC compatible running Microsoft Windows 95 or later, or Windows NT 4.0 or later. It does not work under older versions of Windows NT (such as 3.51), nor does it run under 16- bit versions of Windows (3.1, 3.11, etc) .
3 The flowchart editor required JRE 1.1 to be installed on your system.
4 You can download the latest version of JRE 1.1 from http://java.sun.com/products/jdk/1.1/jre.

Berkeley Madonna Windows
Berkeley Madonna uses various kinds of windows to represent your model including equation, flowchart, parameter, graph, datasets, and notes windows.

The Equation Window
You use the equation window to edit your model’s equations. The editor is a simple plain text editor similar to SimpleText [Macintosh] or Notepad [Windows]. The equation window can be displayed at any time by choosing Equations from the Model menu.
When you create a new model using the New command in the File menu, Berkeley Madonna creates a new, untitled equation window. Similarly, when you open a plain text file, it creates a new, untitled equation window showing the file’s contents.
