Simscape subsystem: How to declare large parameters

Hi,

I am creating a library of simscape blocks which is mainly for internal use. Nevertheless, I want to be able to send protected versions of the individual blocks to customers as well. I protect the models via subsystem2ssc and then ssc_mirror.

The library components are masked subsystems containing only simscape blocks from the default library.

So I spent some time thinking about where to store the block parameters. I decided to declare them in the mask initialization, so they are bound to the subsystem and when I create a protected model of the subsystem, the parameters do not get lost. This works fine so far.

My problem is: Sometimes the parameters can be big arrays. I.e. for a 2d-Lookup Table with 1000x1000 entries, one parameter would have the dimension 1000x1000. It is a quite big effort to copy-paste the values into the mask initialization window.

A solution would be to store this big array in a .CSV - file, and call this file in the mask initialization (i.e. param1 = csvread('parameter_array.csv');). But then when I protect the subsystem and send it to a customer, the parameters are missing because the CSV-file is not attached to the subsystem.

Do you have a better idea on how to declare a large array as a parameter in a simscape subsystem?
