Re: [Numpy-discussion] Strange crash in numpy.linalg.lstsq.

Right... So I was able to get everything working finally. I am not 100% sure how or why it works though so I am going to outline what I did here for reference. I first tried just using LAPACK 3.1.1 (since it seemed set up for g77 instead of gfortran which I do not have). I compiled this to yield

[Numpy-discussion] how can i optimize this function further more?

hello, i'm fairly new to numpy. i need help with a snow effect done with pygame. the entire code is below. the performance drops in the snowfall function. the original c code and a demo can be found here : http://sol.gfxile.net/gp/ch04.html as you can see. the original c code went the pixel by pix

[Numpy-discussion] indexing problem

Hi, Suppose I have a 3-dimansional array, where one dimension is time. I'm not particularly interested in selecting specific moments in time, so most of the time I won't be indexing this dimension. Intuitively, one would make time the third dimension, but if you do that you have to specifiy the t
