Unable to understand the source of erroneous output

I know this is a huge ask but it is for an assignment that's due soon and I am unable to figure out the source of the erroneous output iin my code.

I have built a predictive basketball trajectory model. The methodology is as follows-

1. I first generate a 3D matrix (Sample_Space) which contains all the trajectories possible from the specified initital y posn (Height_Shooter)
2. I then check for the minimum acceptable angle to prevent the shot from being blocked (AngleSelector)
3. Thereafter I use the func PredictedValues to generate suitable launch angles and velocities for a successful 3pt shot

Where the error occurs:

One instance of the error is when Height_Shooter = 1.7, Height_Defender = 2.1, Separation = 0.3

I have attached a screenshot of the error. I don't know why the 2nd trajectory is working with 36 degrees when the min angle is 58 degrees

I suspect the error lies in PredictedValues and I have tried using a breakpoint and runniing through the entire loop but in vain.

I will be super grateful if you could help me fix this, thank you!

Tried to look into it, but got the following error

Unrecognized function or variable 'ballmodel_complex'.

Error in odearguments (line 92)
f0 = ode(t0,y0,args{:});   % ODE15I sets args{1} to yp0.

Error in ode45 (line 107)
