How to use object instances in embedded matlab function

I have question very similar to the below four year old post.
I have a similar problem. Interpreted matlab function block serves the purpose but it slows down the simulation. I tried using 'coder.extrinsic' in embedded matlab function block but i get list of error in 'make', 'parse' and 'coder'.
Problem Description: I have loaded an object called 'ice' in 'masked workspace'. I want to call 'ice.Tmax(u)' in simulink (where 'u' changes with time). Interpreted matlab function block works fine, but it slows down the simulation. I have many such blocks in my model, so i want to use some other block that is quick.
How do i use embedded matlab function block for this purpose ? I tried assigning the object to base workspace and then use 'coder.extrinsic' but i get error as mentioned above.

If you find that is not fast enough then you will need to use a MATLAB Function Block, which will go through Code Generation when you Build your model. coder.extrinsic is part of Code Generation. I think MATLAB Function Block was formerly called Embedded MATLAB Function Block but that changed a few years ago.

Since "ice" is already a variable visible inside that mask, you could create a parameter in the MATLAB Function block, as shown here:
