What's the most “functional” way to do Cholesky decomposition? I guess it's because my code fails to work whenever a zero has been previously computed on the leading diagonal of the lower triangular matrix. I should have added an exception, but I was probably too lazy to do it at the time. :D I'm just wondering if there are any precision issues involved or if you are actually "supposed to" have a zero in that element, though. |

Why is my animation so slow? The Simplify is actually one my futile attempts at making this thing run faster. I have noticed that the problem is probably in the ParametricPlot3D, as it is present even if I do not combine the two plots, only using the former. This might actually be meaningful. |

Why is my animation so slow? I use MMA 8.0.1.0 on an Intel i3 machine running Windows 7, with 4GB DDR3 and a NVIDIA GeForce 310M. I am not sure what kinds of Timings would be useful, since the problem is not that it takes time to start, but rather that the animation looks very much "stop motion"-like. However, I have noticed that it strongly depends on the number of "particles" whose trajectory I track: this slowing becomes negligible at a RandomSample of about 10. |

Manipulating an arbitrary-precision ContourPlot Yeah, you are right. I hadn't thought about that. Since it is an input value, it is only as good as I can input it, and as it stands I can still use higher precision numbers via the input field under the slider if needed. Thanks! So, basically, there is no way to tell the Manipulate function to feed higher-precision numbers to its arguments "internally". Is this right? |
