How to plot two trajectories in Matlab?

I'm trying to plot two different trajectories on the same plot, but it's not working and the graphs are sitting in the III and IV quadrant for some reason. Why Isn't it working?

T=[0:10:3000];
function [xa,ya]= trajectory(VoA,ThetaA,T,g)
%Use formula (3) for xa
xa=VoA*cosd(ThetaA)*T;
%Use formula (1) for ya
ya=(VoA*sind(ThetaA)*T)-(0.5*g*T.^2)+2000;
plot(xa,ya)
end
[xa,ya]= trajectory(VoA,ThetaA,T,g)
hold on
function [xb,yb]= trajectory(VoB,ThetaB,T,g)
%Use formula (1) for yb
yb=(VoB*sind(ThetaB))*T-(0.5*g*T.^2);
%Use formula (5) for xb
xb=xoa-(VoB*cosd(ThetaB)*T);
plot(xb,yb)
end
[xb,yb]= trajectory(VoB,ThetaB,T,g)
P= InterX([xa;ya],[xb;yb])

@ Sarah Hamdan,

VoA, ThetaA and VoB, ThetaB.. where are you defining them?

@ Sarah Hamdan

Ok study the attached code.

Hello Sarah Hamdan,

1. Don't paste code as a image, use option 'Insert aline code'
2. Don't 2 different function body with same function name .
3. Don't use both script and function in same file.

Here is the solution ...

% 521560-how-to-plot-two-trajectories-in-matlab

function MA521560
[xA, yA] = trackA;
plot(xA,yA);
hold on;
[xB, yB] = trackB;
plot(xB,yB);

P = InterX([xA;yA],[xB;yB]);
plot(xA,yA,xB,yB,P(1,:),P(2,:),'ro');
hold off;
end

function [xA, yA] = trackA
xA = randi(10,[1,10]);
yA = randi(10,[1,10]);
end

function [xB, yB] = trackB
xB = randi(10,[1,10]);
yB = randi(10,[1,10]);
end

Replace trackA and trackB function body with your code.

trackA is your trajectoryA function

function [xa,ya] = trajectoryA(VoA,ThetaA,T,g)
%Use formula (3) for xa
xa = VoA*cosd(ThetaA)*T;
%Use formula (1) for ya
ya = (VoA*sind(ThetaA)*T)-(0.5*g*T.^2)+2000;
end
