How to create matrix using for loop and if statment

How Can I create for loop to fix "Matrix dimensions must agree." problem by picking a number from range 1 to 24 and simulate it.

clc
clear all
number_of_the_yearly_day = 1:1:365; %n
T=1:1:24;
declination=23.45.*sin((2.*pi.*(number_of_the_yearly_day-80))./(365));%?
latitude=31.963158; %?
Zenith_angle=latitude-declination; %??
tilt_angle=Zenith_angle;%?
altitude=1-Zenith_angle;  %?
w=15.*(12-T);
Y=acosd(sin(altitude).*sin(latitude)-sin(declination)./(cos(altitude).*cos(latitude)));
X=asind(sin(declination).*sin(latitude)+cos(latitude).*cos(declination).*cos(w));
plot (X,Y)

when I simulate this it gives me "Matrix dimensions must agree.".

number_of_the_yearly_day = 1:1:365; %n
T=1:1:24;
declination=23.45.*sin((2.*pi.*(number_of_the_yearly_day-80))./(365));%?
latitude=31.963158; %?
Zenith_angle=latitude-declination; %??
tilt_angle=Zenith_angle;%?
altitude=1-Zenith_angle;  %?
w=15.*(12-T);

[declination,w] = meshgrid(declination,w) ; 

Y=acosd(sin(altitude).*sin(latitude)-sin(declination)./(cos(altitude).*cos(latitude)));
X=asind(sin(declination).*sin(latitude)+cos(latitude).*cos(declination).*cos(w));
plot(X',Y')
