Why GIF? It - uses a lot of bandwidth - is rather low-quality - would have to be generated server-side, or - if done client-side, is completely redundant vs. canvas, SVG, WebGL, or any of the other client-side technologies for animation/rendering. What animations are you talking

It is mentioned in the IMPROVING PLOTTING MODULE section of GSOC'14 ideas. Okay GIF should not be used...i am going through Three.js and we can add mouse actions which along with d3.js will be nice. I think animations will not be needed anymore then.. But the question is still there..can you

Re: [sympy] GSOC - Step-by-Step calculations

2014-03-02 Thread bl0ckedusersoft
Hello I've made a little progress today. I made a little program (https://raw.github.com/bl0ckeduser/sympy/master/test.py) that tracks the stack frames of all calls to _eval_derivative and prints out their inputs and outputs, as the Wiki suggested. The output for that exact task looks

I find this very encouraging. Some thoughts: 1. Rather than accumulate a list of transformations is it possible to accumulate a tree? Rather than infer which transformations were sub-transformations of others by looking for sub-expressions I wonder if we can collect this information directly.

Hadn't seen nodepy yet. Looks cool, but I'm guessing it is slow. So connecting something like that to theano or any other low level code generator, JIT would be awesome. The ideal case is that we have a super sweet high level interface for solving ODEs that runs as fast as it can. Jason

Nodepy doesn't actually solve ODEs :) It's more of a catalog of ODE algorithms. On Sun, Mar 2, 2014 at 10:16 AM, Jason Moore moorepa...@gmail.com wrote: Hadn't seen nodepy yet. Looks cool, but I'm guessing it is slow. So connecting something like that to theano or any other low level code
