hey
i want to write a code to calculate the Tidal acceleration in 3 ways
A: Sun and moon in the equatorial plane. Centers of mass of the sun, moon and earth and point P are on a line (center of mass of the earth - P - moon - sun)
.B: Sun and moon in the equatorial plane. The centers of mass of the sun, moon and earth and point P are on a line (P - center of mass of the earth - moon - sun)
.C: Sun and moon in the equatorial plane (as above). Point P is at the North Pole.
i wanted to write a code with case condition but i dont know how to call it, i wanna say if case =A then do this
also i have no idea how to write the vector on Matlab ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/487168/image.png)

function [a_t] = gezeitenbesch(G,M_m,M_s,r_e,r_m,r_s)
a_g1 = G*M_m/((r_m)^2);
a_g2 = G*M_s/((r_s)^2);
a_g3 = G*M_s/((r_s+r_e)^2);
a_t1 =a_g1-a_g3;
a_t2 =a_g2-a_g3;
a_t = a_t1+a_t2;
end
% Gravitationsbeschleunigung
G = 6.67408e-11; %[m3/kgs2]
M_m = 7.3483e22 ;% [kg]
M_s = 1.989e30; %[Kg]
r_m = 3.8440*10^8; % [m]
r_s = 1.496*10^11 ; %[m]^3;
r_e = 6378*10^3;
a_t =gezeitenbesch(G,M_m,M_s,r_e,r_m,r_s)
is there any way to plot it ?
thanks
