MATLAB: Does the array only work once

MATLABmuliplevaluevariable

Hey guys,
I'm having trouble with the code in trying to find the angle phi. The calculation for AD uses Theta as I intended, but when calculating Phi, I only get one answer instead of multiple. This makes the rest of my code incorrect. Any suggestions?
% Givens
AB = 150;
BD = 200;
Theta = 20:120;
Mb = 2.5;
%Solutions
AD = sqrt(BD^2 + AB^2-2*BD*AB*cosd(Theta));
%Finding angle Phi of force P
    
Phi = asind(AB*sind(Theta)/AD);
%Finding force P
P = Mb/(BD*sind(90 - Phi));
%Finding Ma
Ma = P * AD;

Best Answer

Use element-wise division: 
Phi = asind(AB*sind(Theta)./AD);
                          ↑ ← HERE
and: 
P = Mb./(BD*sind(90 - Phi));
      ↑ ← HERE
and element-wide multiplication: 
Ma = P .* AD;
       ↑ ← HERE
and the calculations do what you want them to do.
