coswm has a dimension of 1x1, while it needs to be 1x365. what am i doing wrong?

close all
clear all
h=[1:24];%hours in day
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
njul=202; %21 juli is de 202e dag van het jaar
p=52.3667; %altitude amsterdam
heigthblock=25; %heigth of the block in mETER
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
