How to generate 3D plots in Matlab ?

Use 'surf' command in Matlab

Example:

figure;

x = 1:100;

y = 1:100;

z = magic(100);

surf(x,y,z);

Another example to plot the correlation values of the GPS signal:

figure;

% fSamp = sampling frequency

% fCode = 1.023e6;

% fIf = Intermediate frequency, carFreqs -- dopplers

% x - chip axis

% y - frequency axis

% z - correlation values

x = (1:1:fSamp*1e-3)*fCode./fSamp;

y = carFreqs - fIf;

surf(x,y,abs(corrVal));
