MATLAB: Sine wave function

Question

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

Thanks a lot

Answer 1

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);
