R12 Release Notes    

Platform Limitations

For Release 12, all the features described in these Release Notes and in the Release 12 documentation are supported in full for the following platforms:

For details about each of these platforms, see the Support page of the MathWorks Web page, at http://www.mathworks.com.

Differences for the HP and IBM Platforms

Because of problems with the Java VM, there are limitations for MATLAB on the HP and IBM platforms.

Platform
 Limitations
HP 11.0 (HP UX)
IBM
 Graphical user interfaces that are based on Java, such as the MATLAB desktop, are not available.
HP 10.2 (HP 700)
 Java-based tools and applications are not supported.

Alternatives for most tools are available and are documented in the following table. The table summarizes the products with limitations for these platforms. For details on limitations and the alternatives, see the sections of the online version of the Release Notes for the product(s) of interest to you. If a product is not listed in the following table, it has no platform limitations.

Product
 Limitations on HP and IBM Platforms
MATLAB
  • Development Environment
 The MATLAB desktop and many of its tools are not supported. For details, see Development Environment Limitations in the MATLAB section of the online Release Notes.
  • Mathematics
 The Basic Fitting interface is not supported. Instead, use the command line curve fitting capabilities.
  • Graphics
 The Property Editor and Data Statistics tool are not supported. For details, see Graphics and Printing Limitations in the MATLAB section of the online Release Notes.
  • Printing
 The Release 11 Page Setup, Print Setup, and Print dialog boxes are used.
  • GUIDE
 Not supported. Instead, use functions to create graphical user interfaces.
Simulink
 The following Simulink features are not supported:
  • Simulink Editor's Find dialog. Use the find_system command instead.
  • GUI interface to the Simulink Debugger. Use the command-line interface instead.
  • The View Changes dialog box for modified library links. See Platform Limitations for HP and IBM in the Simulink section of the online Release Notes for an alternative.
  • Parameter dialog for the Configurable Subsystem block. Use the set_param command instead to set the block's parameters.
Real-Time Workshop
 Instead of the Model Parameter Configuration dialog box, the Tunable Parameters dialog box is used.
Control System Toolbox
 The Toolbox Preferences Editor and Response Property Editor are not supported. The LTI Viewer Preferences Editor is supported with a reduced set of features (no tools to set preferences for grids, fonts, colors, or phase wrapping).
The following features are not supported for the SISO Design Tool:
  • Preference and property editing
  • Compensator Format editing
  • Storing and retrieving compensators
In addition, the SISO Tool Export window has fewer choices available for export.
Database Toolbox
 Not supported on the HP 10.2 (HP 700) platform.
DSP Blockset
 Same limitations as Simulink.
Filter Design Toolbox
 Not supported on the HP 10.2 (HP 700) platform.
MATLAB C/C++ Graphics Library
 Not supported on the IBM RS/6000 platform.
Neural Network Toolbox
 The Neural Network Tool, a graphical user interface for the Neural Network Toolbox, is not supported. You can achieve the same functionality by using the MATLAB Command Window.
Requirements Management Interface
 Not supported.
Simulink Performance Tools
 The Model Differences Tool is not supported.

Problems Entering Accented Characters on Linux

On Linux platforms, using an accent key to accent a character in a two-stroke sequence in a MATLAB window, such as ^e for ê or ~n for ñ, may cause MATLAB to hang. To avoid this problem in MATLAB, use matlab -nodesktop. With Simulink, avoid the use of these keystrokes. To use characters such as the caret ^ when it is mapped as a dead-accent key, you must paste it into the MATLAB IDE from a non-MATLAB window such as an xterm or use the power and mpower functions directly.

This problem will be addressed in the next release of MATLAB.

Problems Entering Accented Characters on UNIX Platforms

Keys for accented characters, such as Ü on German keyboards and Å on Swedish keyboards are ignored in the IDE. Pasting these characters into MATLAB windows results in the character value 128 instead of the actual character value. For example, pasting the string double('ÅÄÖåäöü') into MATLAB appears as:

This problem will be addressed in the next release of MATLAB.
