Note that the program is subject of modification/correction , An update might take place.

Usage :
function Y=Partial_doa(N,P,L,Theta,s,v,Fc)
Theta is vector of length=P;

Demo.m :

Number of sources : P=2;
Number of samples : L=100;
AWGN variance : v=10;
Frequency of sig : Fc=1e+6;
Signal wavelength : l=c/Fc. ( c: speed of light)
Distance ULA : d=l/2;
Angles of arrival : Theta=[10 45];
