MATLAB: 3D surface (sine wave)

sine wave

Hello, How can I create 3D surface (sine wave)and plote it? Thank you very much

One possibility is to use the following:

k1 = 1; %how many times you want wave to oscillate in x-dir
k2 = 0; %how many times you want wave to oscillate in y-dir
[X,Y] = meshgrid(linspace(-pi,pi));
Z = cos(k1*X).*cos(k2*Y);

Change k1 and k2 for fun.

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);
