Create a function from another function with less parameters

I have a function, let's call it "myFunc". myFunc accepts two parameters, x and y. I want to create a new function "myFunc2", based on myFunc, with one parameter set to a certain value. (e.g x=1)

My final goal is to be able to call the function fzero, passing Myfunc2, that will be function of y only.

Is it possible? I also accept different solutions for achieving this. Thanks in advance

You can use an anonymous function.

addMe = @plus; % the plus function (equivalent of the + operator) accepts two inputs
addOne = @(x) addMe(x, 1); % accepts one input x and returns x+1

addMe(2, 3) % returns 5
addOne(2) % returns 3

Thanks, this is the solution I was searching for, it was even shown in the examples of fzero, but somehow I missed it.

Dave - try nesting the second function within the first (see nested functions for details. For example,

 function [] = myFunc(x,y)

     function [v] = myFunc2(z)
         % since nested within myFunc, it has access to x
         v = z + x;
     end

    % call myFunc2
    fprintf('%d\n',myFunc2(42));
 end

Of course, you would use fzero instead.

Thanks for the answer, but I forgot to mention that myFunc is generated during run time. Anyway, I will keep this in mind for the future.
