Hello,
I need the function for the sine wave if
x= 4000
y= 3000
mean level = 1003
Amplitude = 3
Wavelength = 100
Thanks a lot

what are x and y ? generally, according to your wavelength if you're talking about radio signals in free space, then the frequency of the sine is f = c/Wavelength (c=3e8). you then need to set sampling frequency, i.e fs = 5*f;
and just have sine = mean level + 3*sin(2*pi*f*[1:whatever length]/fs);

Are this correct?
x = 2; % Sets the resolution (step length), in µm, along the x-axis. y = 2; % Sets the resolution (step length), in µm, along the y-axis. z = 1; % Sets the resolution (step length), in µm, along the z-axis. xLength = 4000; % Sets the length of the surface in X. yLength = 3000; % Sets the length of the surface in Y. wavelength = 100; f = 3*sin(x*2*pi/wavelength*[1:4000]) + 1003; % The function for the sine wave with the % amplitude 3 µm and wave length of about 100 µm. Mean level is % 1003 µm.
I can not plot this function.

From your first question I understood as you need a 1-D sine wave.
What is the analytic function that describes your problem?

Creates a matrix describing 3D surface and print it. Thank you so much for your time.
