hi please help me, how to calculate the angle using loop
%Calculate angle
%Loop1
if azA,azB>90;
azA1=180-azA;
azB1=180-azB;
elseif azA,azB<90;
azA1=azA-0;
azB1=azB-0;
end
%Second LOOP
if azA,azB<270;
azA1=azA-180;
azB1=azB-180;
elseif azA,azB>270;
azA1=360azA;
azB1=360-azB;
end

Your syntax usage is incorrect in the if and elseif statements. And this aren't loops, they are conditional statements. As for anything else, your question is unclear? What do you want to do exactly?
Thank you for mention about my mistake about using if and elseif statement. Actually, i have a 2 set of data which is azimuth A and azimuth B. i need to calculate the angle based on this 2 azimuth. I insert the azimuth A and B by using text file. Can you help me?
This in my input coding
obs = load ('obs.txt')
azA = obs(:,1);
azB = obs(:,2);

If your assignment requires loop only, then here is a brief solution that can be extended a bit with some comments:
azA = input('Angle for azA: ');
azB = input('Angle for azB: ');
if azA>90 && azB>90
azA1=180-azA;
azB1=180-azB;
elseif azA<90 && azB<90
azA1=azA-0;
azB1=azB-0;
end
%% Second LOOP
if azA<270 && azB<270
azA1=azA-180;
azB1=azB-180;
elseif azA>270 &&azB>270
azA1=360-azA;
azB1=360-azB;
end

this my solution
%Calculate Angle P
if azA>90 && azA<180
azA1=180-azA;
elseif azA>0 && azA<90
azA1=90-azA;
end
%% Second LOOP
if azB>90 && azB<180
azB1=180-azB;
elseif azB>0 && azB<90
azB1=90-azA;
end
%% Third LOOP
if azA>180 && azA<270
azA1=azA-180;
elseif azA>270 &&azA>270
azA1=azA-270;
end
%% Four LOOP
if azB>180 && azB<270
azB1=azB-180;
elseif azB>270 &&azB>270
azB1=azB-270;
end

That code does not have any loops.
Note that if you have a series of values of azimuth, then you would need to build [for .. end] loop as well.
