MATLAB: Not enough input arguments.

function val notenoughinputarguments

I have a file called F.m which contains the following code:
1    % INPUT:
2    % 3D vector x
3    %
4    % OUTPUT:
5    % function value at x
6    
7    function val = f(x)
8        val= x(1)^2 + x(1)*x(2)^3 - 12*x(3) + 4;
9    end
I am trying to call F.m in an algorithm in another file, but when I run the code, I get the following error:
"Error using F (line 8) Not enough input arguments."
I'm new to MATLAB, so I'm not sure what I'm doing wrong here. Any help would be greatly appreciated!

With the syntax
Algorithm1(F, gradf, [0,1,2], 0.1, 0.1, 10)
MATLAB is looking for a variable named F (and similarly with gradf). You need to tell it that F is a function, by passing the function handle:
Algorithm1(@F, @gradf, [0,1,2], 0.1, 0.1, 10)
It looks like you have similar problems deeper in your code, but I could not resolve them completely because I don't have all the functions you are using.
