I am running an application which involves solving symbolically an ODE over a three segment domain and then adjusting the constants of integration to satisfy boundary/continuity conditions. I wrote the code in document mode and noticed that it takes very long to execute. I resurrected the old worksheet-based code which does basically the same thing and it runs much faster. Of course the code in both cases (due to evolution of both software and user) is not exactly the same.
Now to my question: Does anyone know of a tool (like the one offered by several FORTRAN compilers, e.g., SGI) that would allow you to identify bottlenecks?
thanks so much
