Plotting two variable equation

waveform=sin(3x)-y^3 where x and y vary from -2pi to 2pi.Should look similar to but different from sine wave

This will generate a 3D surface plot

x = -5:0.1:5;  % specify the range of x and y
y = -5:0.1:5;

[X, Y] = meshgrid(x, y);
wave = sin(3*X) - Y.^3;
surf(X, Y, wave);
