How to convert a model than can be run with simulink to a function?

Hello, I have a model that I would like to convert it into a function. The current model can be graphed or expressed via simulink but I would like to know if there is a way that I can convert it into x and y function so that it can be graphed via MATLAB directly.

The model to the link is: http://www.mathworks.com/matlabcentral/fx_files/41141/1/Capture.PNG

Yes it's possible to make a script that do what your model is doing. You have to know the mathematical model of your system, there many tools in Matlab that can resolve several mathematical problems.

Ok. May I know what do you exactly mean by "know the mathematical model"?? I mean when I double click for instance on Vm_(mV) iNaf_(pA), I get the math that was used inside. So am I on the right path that you are talking about??

I mean the relations between outputs and inputs
