MATLAB: How can I use graphical function in chart at C action language？

code generationsimulinkstateflow

this is the stateflow ，i want use graphical function in OFF status，use exteral function in ON status（i set extern C file in configration is ok）。when i use this stateflow make code generation。when i use chart action language MATLAB ，and comment 2 ie.% H=changeH(EXData.h).it ok. but not comment，following errors is occuring.

for use extern function, I search one method ：use chart action language C. but in this action language ，not identify graphical function.How how can I use graphical function in chart at C action language？or other solve method?

I solved this issue. EXData.H data type is default double,but my externfunction is int.....

MATLAB: Using Data Store Memory in Stateflow

I understand that you are trying to write to a Data Store Memory using C action language.

In order to achieve this in "Chart(C)", you can index into the array as follows:

MyData.buffer[0][0] = 1;

C action language follows zero based indexing as opposed to MATLAB action language that follows one based indexing. You can refer to the link below for further information about how to modify the action language of a chart:

You can also refer to the following link that lists the differences between MATLAB and C as Stateflow action language syntax:

MATLAB: How to disable warning for Stateflow action language

It does not seem possible to disable the warning. If you will be using C as the action language throughout the whole model, it looks safer and easier to me to first set the correct action language before adding a new Stateflow chart. I understand that you would like to avoid changing default action language on other people's machine, but a possible workaround could be:

Save their current default setting
Change the Stateflow action language to "C"
Restore the previous default language at the end of the script

The code that does the job should look like:

curLanguage = sfpref('ActionLanguage'); % save the user's current language
sfpref('ActionLanguage','C'); % set the default language to C
% Your code ...
sfpref('ActionLanguage', curLanguage) % restore to previous setting
