I have an .m file which defines a state space and then plots its impulse response. Now, I want to make a Simulink model of this. As I am not familiar with Simulink, can anyone help me in finding an easy way to create a Simulink model directly from the .m file?
Here I provide the code in the .m file:
-------------------------------------------------------
k=11.417;
L=0.8603;
Jm=12e-6;
JI=235e-6;
a=k/Jm;
b=k/JI;
A=[0 1 0 0;-a 0 a 0;0 0 0 1;b 0 -b 0];
B=1/Jm*[0;1;0;0];
C=[0 1 0 0;0 0 0 1];
D=zeros(2,1);
plant=ss(A,B,C,D);
impulse(plant,0.025);
--------------------------------------------------------
Thanks

Short answer,
In general, there is no magic function or button that will convert your MATLAB code into Simulink model. However there maybe some specific toolbox utilities that can help do this for specific functionalities. I am not aware of such a way to create state space models though.
Long answer,
  1. Learn the basics of Simulink. This tutorial might be a good place to start.
  2. In your case, you can try to use the built in State space block in Simulink. Documentation is here.
  3. You can also use the general LTI block in the Control Systems Toolbox to import the 'ss' state space object from the MATLAB base workspace into Simulink. Take a look at its documentation here.
