How to change function coefficients?

Assume there is a function file:

function y = myFun(x)
coef = 1;    
y = coef*x^2;
end

How to change coefficient in another script when calling this function? I know that I can do myFun(coef,x), but I will have then 2 variables (more if x is vector of vars). I want to call in my main script this fubction with changed coefficients:

func = @myFun; % but with changed coef

Following the guidelines given in the MATLAB documentation:

https://www.mathworks.com/help/matlab/math/parameterizing-functions.html

You could use an anonymous function:

function y = myFun(x,coef)
y = coef*x^2;
end

and then:

func = @(x)myFun(x,1);
