=> Integrator a

Internal integrator

-> a

initial value

-> Vector Double

vector of time points

-> m (Vector a)

vector of solution

Integrate ODE equation using fixed steps set by a vector, and returns a vector of solutions corrensdonded to times that was requested. It takes Vector of time points as a parameter and returns a vector of results
