Say I have a system that is $n$ differential equations that are all coupled together, over a time interval $[a,b]$ with timestep $t$. Is there a straightforward time complexity for MATLAB's built in differential equation solvers ode45, ode23, ode15s? Particularly I am interested in how ode15s grows as the size of $n$ increases. Any help is appreciated!
ode15s is "Variable-timestep, variable-order" method, so I have no idea how to determine the complexity
