Question

For the unit 7 Programming Assignment, we will implement a function grapher. Essentially you must create a program that can plot a function that is in the form
z = f(x,y)
Your program must generate input values between -1 and 1 in increments of .1 and use this to plot x, y, and z vertices to be included as part of a mesh that will then be graphically displayed.
If you would like you can implement the functionality to allow both the function to be mapped as expressed as a mathematical formula and the input values to be entered by the user of your program, however, this is optional.

Answer 1

%% MATLAB Code %%

close all;

f = @(x, y) x.^2 + y.^2;
grapher(f);

function grapher(f)
    [X, Y] = meshgrid(-1:.1:1, -1:.1:1);
    mesh(X, Y, f(X, Y));
end
