Re: [Numpy-discussion] How to remove fortran-like loops with numpy?

2009/6/9 Stéfan van der Walt ste...@sun.ac.za: Hi Juan ---cut --- As you can see, it is very simple, but it takes several seconds running just to create a 200x200 plot. Fortran takes same time to create a 2000x2000 plot, around 100 times faster... So the question is, do you know how to

[Numpy-discussion] How to remove fortran-like loops with numpy?

Hi all, I'm new in numpy. Actually, I'm new in Python. In order to learn a bit, I want to create a program to plot the Mandelbrot set. This program is quite simple, and I have already programmed it. The problem is that I come from fortran, so I use to think in for loops. I know that it is not the
