Real-Time Workshop 4.1 Release Notes

Build Directory Validation

The build process now disallows building programs in the MATLAB directory tree. If you attempt to generate code in the MATLAB directory tree, an error message will be displayed prompting you to change to a working directory that is not in the MATLAB directory tree. On a PC, you can continue to build in the directory matlabroot/Work .

The build process also prevents building programs when matlabroot has a dollar sign ( $ ) in its MATLAB directory name.

Build Subsystem Enhancements

The Build Subsystem feature, introduced in Real-Time Workshop 4.0, lets you generate code and build an executable from any nonvirtual subsystem within a model. In Real-Time Workshop 4.1, the Build Subsystem feature has been enhanced as follows:

• The Build Subsystem window now displays additional information about block parameters referenced by the subsystem.

• From the Build Subsystem window, you can now inline any parameter or set the storage class of any parameter.

See “Generating Code and Executables from Subsystems” in the Real-Time

Workshop User’s Guide for further information.

C API for Parameter Tuning Documented

The Real-Time Workshop provides data structures and a C API that enable a running program to access model parameters without use of external mode.

This API has now been fully documented.

To access model parameters via the C API, you generate a model-specific parameter mapping file, model_pt.c

. This file contains parameter mapping arrays containing information required for parameter tuning.

See “C API for Parameter Tuning” in the Real-Time Workshop User’s Guide for information on how to generate and use the parameter mapping file.
