Hi,
I have a generic Matlab function describing the behaviour of an battery electrode and I would like to call it in my model with various parameters (one call for the positive electrode, and the other call for the negative electrode calculation).
In order to make my function generic, I use a structure that contains parameters of the positive and negative electrode so that calling it with argument "pos" or "neg" will make the calculations with whether positive or negative parameters. Unfortunately, Simulink sees that as a "non constant parameter" and refuses to operate.
Do you have an idea of a way to call my "unique function" twice in my model: one call for the negative electrode and an other call for the positive one?
Thanks!

In other words, I have two sets of parameters (one for the positive electrode and another for the negative electrode), and I want to call a Matlab function with those two sets, without having to copy/duplicate the block.
For this matter, I was using a Data Dictionary containing each parameter as a structure with two fields : pos and neg.
Unfortunately, Simulink won't let you use the syntax "Param.(Electrode)" in a Matlab Function Block.

Use a Constant Block of signal type Boolean feeding into that parameter ?
Boolean because Simulink does not support signals that are type string.

Right, this is what I've finally done. But I'm still not very confident with the way I manage my parameters (Data Dictionary and Structures). Is there some Best Practices for using parameters of that kind in a Simulink Model?
Thank you again for your time.

Sorry I do not know about that.
