My Simulink workspace looks like this:
and the function contains just a few lines:
function y = mysimulinkfunction(u,v)
%#codegen
global net;
y = net([u;v]);
The object "net" is an already trained feed forward network residing in my workspace which can be successfully called from the command line via
net([1;0])
and writes the correct answer (which is 1.0).
However Simulink throws several errors when I try to run it, first:
Global declaration not resolved to a Data Store Memory block registered via the Ports and Data Manager.
and 2nd:
Could not find initial value for global variable 'net'.
Those errors sound like it is not possible to call neural networks that way, however I just want to know if there's another possibility than gensim(net) to use a NN in Simulink.

In the MATLAB Function Block global variables are linked to Data Store Memory blocks rather than the MATLAB workspace:
However, I don't believe that Neural Network objects are directly supported for code generation.
The simplest alternative to gensim I've seen to utilize a trained NN in the MATLAB Function Block or MATLAB Coder is genFunction:
That page describes how to create a MATLAB Function Block/MATLAB Coder compliant MATLAB function via the syntax:
genFunction(___,'MatrixOnly','yes')
This will produce a MATLAB function which you should simply be able to call from inside your MATLAB Function Block to simulate the NN.

Hey, is there any way to use "SeriesNetwork" in Simulink?

were you able to find a way to do that?

Not yet. It seems up to now, there is no (simple) way...

How I can put these numeres in equation?
