coswm should have a 1x365 dimension, but its dimension is 1x1, what am i doing wrong?

m=[1:14400];%minutes in day
n_param=5;
n=[1:365];%days in year
az=0.0001; % degrees %a=0,001 , because a is near zero during sunrise and sunset.
ndec=355; %21 december is de 335e dag van het jaar

sino=zeros(1,365);
max_loops = 100;
for n_days=n %azimuth angle
sinoaz=-23.45*(pi/180)*cos(((2*pi)/365)*(10+n));
oaz=asin(sinoaz);
%wm=(m+7200)*pi/7200;
%sin(a)=cos(o)*cos(wh)*cos(p)+sino*sin(p)
%sin(a)-sino*sin(p)=cos(o)*cos(wh)*cos(p)
%cos(wh)=(sin(a)-sino*sin(p))/((cos(o)*cos(p)))
coswm=(sind(az)-(sinoaz*sind(p)))/((cos(oaz)*cosd(p)));
wmaz=acos(coswm);
sinaaz=sind(az);
sinAz=(sind(wmaz)*cosd(oaz))/sinaaz;
Az=asind(sinAz);
end

The / operator is Matrix Right Divide, which is least squares fitting effectively. If you did not intend to do fitting at that point then you probably want the ./ operator which is element by element division.
