Version 6.4 (R2006a) Stateflow® and Stateflow® Coder™ Software Release Notes

Version 6.4 (R2006a) Stateflow and Stateflow Coder Software

This table summarizes what's new in V6.4 (R2006a):

New features and changes introduced in this version are described here:

Option to Initialize Outputs When Chart Wakes Up

You can use a new chart option Initialize Outputs Every Time Chart Wakes Up. Use this to initialize the value of outputs every time a chart wakes up, not only at time 0 (see Setting Properties for Individual Charts in the online documentation). When you enable this option, outputs are reset whenever the chart is triggered, whether by a function call, edge trigger, or clock tick. The option ensures that outputs are defined in every chart execution and prevents latching of outputs.

Ability to Customize the Stateflow User Interface

You can use M-code to perform the following customizations of the standard Stateflow user interface:

• Add items and submenus that execute custom commands in the Stateflow Editor

• Disable or hide menu items in the Stateflow Editor

See Customizing the Stateflow Editor in the online documentation.

Using the MATLAB Workspace Browser for Debugging Stateflow Charts

The MATLAB Workspace Browser is no longer available for debugging Stateflow charts. To view Stateflow data values at breakpoints during simulation, use the MATLAB command line or the Browse Data window in the Stateflow Debugger.

Chart and Truth Table Blocks Require C Compiler for 64-Bit Windows Operating Systems

No C compiler ships with Stateflow software for 64-bit Windows^® operating systems. Because Stateflow software performs simulation through code generation, you must supply your own MEX-supported C compiler if you wish to use Stateflow Chart and Truth Table blocks. The C compilers available at the time of this writing for 64-bit Windows operating systems include the Microsoft^® Platform SDK and the Microsoft^® Visual Studio^® development system.
