maybe it will be faster if you try parallelizing the calculation with "parpool" in the command window, good luck!

Igor Faddeenkov

You might change the deltaT to a bigger value to accelerate the calculation.

Other than that, the actual choice of solver in Matlab depends on the "type" of your ODE.

Please find attached a screenshot of the Matlab documentation of the different solvers.

You differentiate normally between "stiff" and "non-stiff" odes and then there are difference on a lower granularity level.
