Berkeley Madonna 8.3.18
The software is fully functional with the following exceptions:
- Models cannot be saved.
- Graphs and tables cannot be saved or copied.
- A watermark appears in all printouts.
- The Register dialog appears each time the program is started.
When you purchase a Berkeley Madonna license, we’ll send you a registration number which removes these restrictions. We’ll also send you a copy of the Berkeley Madonna User’s Guide in Adobe Acrobat format.
For complete instructions on purchasing a Berkeley Madonna license, refer to the Read Me file in the download package or the How to Purchase page.
Berkeley Madonna has been tested on personal computers with Intel x86 and 64 bit or compatible processors under Microsoft Windows XP, Windows 7, Windows Server 2008, Windows Server 2012, however may work with other versions of these operating systems.
Error in documentation for normal random number syntax
The correct syntax for generating a random number y with a normal distribution is y = normal(µ, sd) where µ is the mean and sd is the standard deviation. Older versions of the Equation Help menu as well as the User’s Guide erroneously stated that the second argument was the variance. This has been corrected in both Equation Help and User’s Guide as of 1/13/2010
What’s going on with Berkeley Madonna
The compute engine of Berkeley Madonna was originally written in C, and later extended with the Flowchart graphical interface written in Java. Because of changes in Apple’s Java implementation in OS X, it has been difficult to retain the same architecture on the Macintosh as in Windows.
A version of Berkeley Madonna, called JMadonna, is in development. It will have the user interface written in Java, while retaining the simulation engine in C for speed. This will allow us to extend Berkeley Madonna in many ways, including a Linux version. Before JMadonna is released, however, we are releasing an interim version of Madonna (8.3) for Windows and Macintosh with support for global variables in the Flowchart, nullclines on the phase plane (see below),as well as an improved Fourier transform, an improved pulse function and a more efficient web-based registration through Kagi.
The PC version works well in most versions of Windows. The Flowchart in the Mac version, however, works only in OS 10.4 (Tiger). The equation-only version works in all versions of OS X.
Globals: Flowchart – Equation Window Hybridization
A “globals” dialog has been added which allows you to add equation definitions directly into the equation window without having to create flow chart icons. (Windows and Mac). These definitions are globally available to all icons in the flow chart through their usual dialogs. This can be used to reduce flow chart clutter by moving all secondary definitions off the flow chart into the equation window. E.g. use it for dimensional definitions, physical constants, secondary parameters and variables, etc. An example is given in the program under Help > How do I> Use global variables
Nullclines: where derivatives change sign
Using a phase plane plot with a second order system, you can display the nullclines simply by clicking on the Nc button in the graph toolbar. The legend button identifies each nullcline. An example is given in the program under Help > How do I>Plot Nullclines
