fsolve using MATLAB Simulink

This is a code and a model for using fsolve function with MATLAB and Simulink. The both method are equivalent and give the same results. There are three types:
1- Basic : fsolve example (MATLAB & Simulink).
2- fsolve example (MATLAB & Simulink)- Inherent variables.
3- fsolve example (MATLAB & Simulink)- Inherent variables - Vector Input.
Note: run the main.m file for the first time to enable using the Simulink model.
