Ran in:
I have no idea what you are asking.
It is straightforward to create a function handle that accepts various function arguments, either for a specific function or an existing function.
f = @(x,y) exp(-(x.^2 + y.^2)/5);
[X,Y] = ndgrid(-5:0.1:5);
figure
surf(X, Y, f(X,Y))
grid on
.

I have this: f=@(v1,v2,v3)(v1*v2^2+v3)
This is particular, but i want to create different functions in a loop.
for example if i=1 the f has this form, but if i=2 the format have to change in (v2*v3^2+v1).
So i need a dynamic f.

Create the functions you want, then use an if, elseif, else block to choose the function to execute with respect to a particular condition.
