[Numpy-discussion] Memory efficient alternative for np.loadtxt and np.genfromtxt

2014-10-26 Thread Saullo Castro
I would like to start working on a memory efficient alternative for np.loadtxt and np.genfromtxt that uses arrays instead of lists to store the data while the file iterator is exhausted. The motivation came from this SO question: http://stackoverflow.com/q/26569852/832621 where for huge arrays t

[Numpy-discussion] Interpolation using `np.interp()` with periodic x-coordinates

2014-09-24 Thread Saullo Castro
>From the closed pull request PR #5109: https://github.com/numpy/numpy/pull/5109 it came out that the a good implementation would be adding a parameter `period`. I would like to know about the community's interest for this implementation. The modification are shown here: https://github.com/saul

[Numpy-discussion] PR #5109 - interpolation function for polar coordinates

2014-09-24 Thread Saullo Castro
Dear all, today I've submitted a pull request: https://github.com/numpy/numpy/pull/5109 in order to include an interpolation function for angular coordinates, since using np.interp for this purpose is cumbersome. I kindly ask for your feedback and/or questions. Greetings, Saullo ___
