Hello,
I'm using MATLAB ODE suite to solve a couple of ODEs. I watched the webinar (https://www.mathworks.com/videos/series/solving-odes-in-matlab-117658.html) and it was really helpful!
I have some instances where the integrand becomes 0/0 (e.g. dy/dt = A*sin(t) / B*sin(y) where y=0 at t=0 and y=2pi at t=2pi).
Does any of the MATLAB ODE solver implement the L'Hospital rule for such cases? If not, what would be the best way to implement this (with ODE45 or ODE15S for example)?

Yeah, I wanted to check if any solver already has this condition implemented [i.e. if @F(t,y) = f(t) / f(y) = 0/0, then use f'(t) / f'(y)]

No numerical solver will have this feature. It will simply give you a division-by-zero error message.
