comment Correct use of Solve inside Compile
Compile isn't the catholicon for speed, the core part of your code is just not compilable. Generally Compile only speed up low level arithmetic calculation, see the link @george2079 gave for more details.

comment Dramatic speed difference of code on Matlab and Mathematica
@zjx1805 I believe you'll manage to improve the complete code if you fully understand the answers you got. BTW, See my edit for another 2X speedup.
