S1 is a 10 x 1 double. and S is 1 x 2 double. I am doing some calculations with those numbers and in the end for my theta I should just get distinct 10 x 1 double array too. But for some reason I am getting 10 x 10 for theta. I don't understand why or how to fix it.
% Calculating the distance from original source location for all locations with error.
sx = S1(:,1) - S(1);
sy = S1(:,2) - S(2);
l = sqrt((sx).^2+ (sy).^2); %distance between original source location and error source locations.
zz = sqrt((S1(:,1)).^2+ (S1(:,2)).^2); % distance of error source locations from origin.
ss = sqrt((S(1)).^2+ (S(2)).^2); %distance of the source from origin.
% Calculating the resolution for a traingle with lengths l, zz, ss
n = (zz.^2 + ss.^2 - l.^2);
d = (2 .* zz .* ss);
theta = acos(n/d);

Use element-wise dividion (./) iunstead of (/) in the acos call —
theta = acos(n./d)
EDIT — See Array vs. Matrix Operations for details.
