Making a 3 Variable Function Into a 1 Variable Function

Hello,

I have created the following simple function of the variable x,a, and b

f = 2*x - a - b.

What I want to do is set a and b equal to some constant values, for example a = b = 1. Now that I have set a and b equal to constants, my question is, how do I make this into a new function with just the variable x? For a = b = 1 , the new function should be 2*x - 2 . I want to do this so that I can use fzero to solve this new function numerically for x. Any help would be much appreciated.

Hi,

have a look at the documentation. So basically

function f=my_fun(x,a,b)
f = 2*x - a - b;

Then you do:

f=@(x) my_fun(x,1,1)

And you call it with f(2) for example.

Thanks a lot Friedrich! This solved my problem! :)
