Extracting entity attributes from a batch and using it as an input to a simulink or matlab function?

In my SimEvents simulation, the entities have an attribute x. I need to compute a function f(input_array) on a 50-element array of x values. I'm using the batch generator block to create a batch of 50 entities, but how do I extract the attribute array to input to f(), which is implemented as a matlab function?

Hi,
According to my understanding you want to access the entity attributes in MATLAB. To do this, You may save the entity attributes to MATLAB workspace using “assignin and then pass it as one of the input arguments to the function as you mentioned.
You can save the entity attributes to MATLAB Workspace by calling the following code in the event actions of a SimEvents Block:
coder.extrinsic('assignin');
assignin('base', 'out’, entity);
“out" is the variable in workspace where the values of entity are saved.
