I am having trouble finding a way to extract data at then end of a for loop with function.
for i = 1:length(height)
% solve coupled drag ODE
options = odeset('RelTol',1e-5,'AbsTol',1e-7); % ODE options
f = @(t,x) horizEqns(Isp,Wo,Wb,Wdot,msl,1,height(i),t,x); % the equations that will be solved
[t,soln] = ode45(f,[0 maxtime],[0. v0],options);
end

You overwrite your t and soln values with each loop iteration. If you want to save those to use them later you need to put them into arrays. Assuming t and soln have the same length each time
[t(:,i),soln(:,i)] = ode45(f,[0 maxtime],[0. v0],options);

Thank you! That second one works. If you add it as an answer outside the comment, I will accept it as the working!
