how to make fuction from changing varibles

Z = @(x,y,z) x.^2 + y.^2 + z.^2;                    % Create ‘Z’
a = linspace(0, pi, 5);                             % Define Vector
b = linspace(440, 3010, 4);                         % Define Vector
c = linspace(0, 4000, 3);                           % Define Vector
[A,B,C] = ndgrid(a,b,c);                            % Create Matrices From Vectors
Zout = Z(A(:),B(:),C(:));                           % Creates Appropriate Column Vectors For All Elements Of Original Vectors
[Zmax,ixmx] = max(sum(Zout,2));
[Zmin,ixmn] = min(sum(Zout,2));

Use your own ‘Z’ and your own method of assessing its values.

can i make from all results kinds of 3D graphs ?

That depends.

If you choose two independent variables and the output of ‘Z’, then probably: Yes.

From my example here:

Z = @(x,y,z) x.^2 + y.^2 + z.^2;                    % Create ‘Z’
a = linspace(0, pi, 5);                             % Define Vector
b = linspace(440, 3010, 4);                         % Define Vector
c = linspace(0, 4000, 3);                           % Define Vector
[A,B,C] = ndgrid(a,b,c);                            % Create Matrices From Vectors
Zout = Z(A(:),B(:),C(:));                           % Creates Appropriate Column Vectors For All Elements Of Original Vectors
[Zmax,ixmx] = max(sum(Zout,2));
[Zmin,ixmn] = min(sum(Zout,2));
Av = A(:);
Bv = B(:);
Zv = Zout(:);
figure
stem3(Av, Bv, Zv,'.')
grid on
