Using global structures in matlab functions block(Simulink)

In the data store memory block, it is not possible to set your variable as a structure since structures are not primitive types. My question is, is there a away to still use global structures in matlab function block?

Thank you very much.

This is infact possible

You can type '*Working with Structures and Bus Signals*' in matlab 2012a documentation to find the missing page. Let me know if that helps.

Hi,

Could you please provide more information about it? Did it work? Thank you

AFAIK, it is not possible to use structure as the global data in matlab function block.

Global data in matlab function block always need to be stored with Data store memory block, and Data store memry block do not support structure.

Also if you are using Simulink.Signal object to scope the global data, type of object should be defined explicitly. It can not be structure.

See Limitations of Using Shared Data in MATLAB Function Blocks.

However if you can explore more detail about your requirement, someone can suggest alternative.

Ok no structurs, thanks alot TAB.

What if I have a global java object which I want to update in matlab function block. How can I access the global java object in the matlab function block.

Thank you

bethel, I am not aware of using java classes with matlab or with simulink. But I don't thing matlab function block supports the use of java classes.

You can post this question in separate thread, may be someone else knows the answer.

Ok, I have done it now using the interpretted matlab block to update the java object, and it works fine.

cheers
