how to use function in fzero as a variable file

Hello,

There's a simple example of fzero here, that defines a function in a file called f.m: https://www.mathworks.com/help/matlab/ref/fzero.html

What I need, is that f.m to be a variable passed into the calling function, because it can be from any file (f.m, f1.m, etc). Matlab complains if i try to pass in f through arguments because it's already used as a function. Is there a trick to it?

Thanks so much,

Dave

Look at this other example instead:

fun = @f; % function
x0 = 2; % initial point
z = fzero(fun,x0)

and if you wanted f1.m then you would use

fun = @f1

But I want to always refer in my main code to @f, where f is the name of a file that is passed in through arguments. Then I don't have to hard code now an @f1 in the main code...

I got that to work. Thank you.
