comment Protected tag in DSolve
Seems this hasn't been done: Hello, welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the faq! 3) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign!

Since you used C compiler, RuntimeOptions -> "Speed" will speed up the code even more.

comment Numerical integration's speed
@yashar Have you checked your task manager? If matlab doesn't use multi-core then the CPU utilization rate should be quite low.

I wonder what's the output of matlab? Is it still reliable?

improve the code a little: I forgot that Rescale isn't compilable.

I think you mistyped the definition of fP?

comment Numerical integration and plotting
By saying “plot C as a function P”, do you mean you want to use P as the independent variable of C?
