MATLAB: Am I unable to change the name of the graphical functions in Stateflow 6.0 (R14)

errorfunctiongraphicalicu_dataMATLABregexpstateflowsyntax

I have a Stateflow chart that worked correctly in Stateflow 5.1.1 (R13SP1). However, upon opening the Stateflow chart in R14, some of my graphical functions exhibit name problems. For example, the names which had been specified for the graphical functions were all changed to "$1".

Upon attempting to set these functions back to their proper function names, I am unable to change them at all and I receive several warnings in the MATLAB Command Window as follows:

 Warning: Syntax error in props.initialValue field of data e (#172)
 Warning: Syntax error in props.initialValue field of data s (#173)
 Warning: Syntax error in props.initialValue field of data t (#174)
 Warning: Syntax error in props.initialValue field of data time (#175)
 Warning: Syntax error in props.initialValue field of data e (#176)
 Warning: Syntax error in props.initialValue field of data s (#177)
 Warning: Syntax error in props.initialValue field of data t (#178)
 Warning: Syntax error in props.initialValue field of data e (#179)

Without these corrections in graphical functions my chart is useless. How can I fix this problem?

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in MATLAB 7.0 (R14) in the way that MATLAB handles an environmental variable called ICU_DATA on the system PATH. For information about how to resolve this issue, see the following solution:

MATLAB: How to pass a variable to a Stateflow chart without having to specify the size of the data parameter in Stateflow 6.3 (R14SP3)

This enhancement has been incorporated in Release 2009b (R2009b). For previous product releases, read below for any possible workarounds:

You can work around this error by setting the size of the Stateflow variable dynamically at runtime. In the Model Explorer, add a script into the InitFcn callback function to set the size of the Stateflow variable "a" every time the model is run.

For this script, you need to obtain handles to Stateflow objects. See the documentation "Using the Stateflow API" available at the following URL:

http://www.mathworks.com/help/stateflow/programmatic-manipulation.html

In particular, the "Quick Start for Stateflow API" through "Accessing Existing Stateflow Objects" sections provide information about accessing object handles.

The following sample code shows how to set the size of Stateflow data

variable "a" to equal the size of MATLAB workspace variable "x", using

commands in the InitFcn callback function:

rt = sfroot;
m = rt.find('-isa','Simulink.BlockDiagram');
onState = m.find('-isa','Stateflow.Data','-and','Name','a');
onState.Props.Array.Size = num2str(length(x));

A sample Stateflow model is attached as an example. To run the model, create a MATLAB workspace variable "x", as in this example:

x = 0:0.1:N;

N can be any number. The Stateflow model outputs the sine of "x" into a MATLAB workspace variable "v". By accessing the handles to objects in the Stateflow chart, you can automatically set the size the Stateflow data parameter "a" to equal the size of the MATLAB workspace variable "x".

MATLAB: Am I experiencing problems with the International Components for Unicode (ICU) libraries in MATLAB 7.0 (R14)

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, read below for any possible workarounds:

MATLAB uses the International Components for Unicode (ICU) libraries to perform some of its string manipulation. Other applications (such as FalconView) which use those libraries may set the system environment variable ICU_DATA. If the other product uses a different version of ICU and sets this environment variable globally, it is likely that MATLAB will exhibit bizarre behavior, particularly related to string handling. To restore string-handling functionality in MATLAB, run MATLAB from a shell that has no ICU_DATA variable set. Here are instructions:

1. Find the location of MATLAB.EXE. In this example, we assume the MATLAB.EXE file exists in the following directory:

d:\Applications\MATLAB7\bin\win32

2. Create a new text file

3. Add the following lines to the text file...

 set ICU_DATA=
 start d:\Applications\MATLAB7\bin\win32\matlab.exe

4. Rename the text file to have a .bat extension, i.e. MATLAB.bat

Double-clicking the BAT file should launch MATLAB with the correct libraries

Alternately, you can launch MATLAB from a shell that has ICU_DATA set to the directory that contains matlab.exe. In this example, that would be

set ICU_DATA=d:\Applications\MATLAB7\bin\win32
start d:\Applications\MATLAB7\bin\win32\matlab.exe
