My suggestion would be to prototype in all-Python first. This will let you work out the kinks of your call/callback interfaces. Then see if the Newton's method part is a bottleneck worth converting to C++. My suspicion is that the performance (for all but trivial functions) will be in the function you are solving for, not in the Newton's metod. So be sure to test with a function that you feel is representative of those you want to solve for, not just a simple parabola. Then, stop thinking in C++. "Function pointer"? A function in Python is an object, a callable. You should be able to just treat it like one. -- Paul -- http://mail.python.org/mailman/listinfo/python-list
