I have written a relatively large simulation in Maple10 and it is literally taking forever to run for any decent size and time. I have been trying to convert to C to run in C, which became a serious problem, then I tried to use "compile" which again was very problematic. They seem to work only when the code is written in a C-like format anyway, in other words to use of lists and very fussy with arrays and procedures within procedures seems to create problems. I just wanted to ask if there is something clever I can do, to convert my procedure (there are about 20 of them) and if there is certain rigorous formatting I can do without having to literary re-write my whole code, as that is the way it seems now.
