How to seperate my function file from my script

Defining Functions in MATLAB: Devices that limit the output voltage to a maximum allowed value A are called clippers. Mathematically, we can represent a clipper by a piecewise function.

I have a working script file which performs the neccessary operations, but I would like to make two files. The logic part with the if statement through the end needs to be in a function file. When performed with the script below, it should have the same output.

Basically, I want to seperate a function file from a script file. I would like to seperate my if statement into a function file which utilizes this script.

This is the script below:

w1=2*pi;% Varaible 1

f1=w1/(2*pi); %frequency of f1

T1 =1/f1;% Period of fxn 1

A=3;

T = T1;

step= T/50; %determines stepsize from smallest period

t = 0:step:4;

v = 5*cos(w1*t);

vclip = v;

for i=1:length(v)

if v(i)>A

vclip(i)=A;

end

if v(i)<-A

vclip(i)=-A;

end

end

plot(t,vclip)
