I have no idea if that possible to in Simulink or not , please help

This is flux linkage-current curve for switch reluctance motor.

Anyone can get this graph (inside block parameters > plot magnatizing curve)

I want to get a formula flux linkage as a function of current for the yellow line(first line), and the blue line (last one)

is that possible??

I need to get something like this for each line .

Is that possible to be done or not ?

I need to generate a function that closely describes the plot that I have.

Given a curve and try to figure out an approximate formular is called curve fitting. Don't do it in Simulink. Do it offline in MATLAB.
