Also note that the expression range(n) is calculated outside the timing brackets - another trick to minimize the overhead caused by the timing function. If you are worried about this overhead, you can calibrate it by calling the timing function with a do-nothing function. import time def timing(f, n, a):...

    Python Success Stories Background MayaVi is an open source scientific data visualization tool written entirely in Python. I started work on MayaVi in 2000. At that time, a few colleagues of mine needed to visualize their computational fluid dynamics (CFD) data but the only suitable tools available were commercial, closed source programs that were prohibitively expensive. We looked at some open source tools as alternatives. OpenDX had just been released to the public and at that time was har...
