Hi all, I am pleased to announce the availability of SciPy 0.10.0. For this release over a 100 tickets and pull requests have been closed, and many new features have been added. Some of the highlights are: - support for Bento as a build system for scipy - generalized and shift-invert eigenval

(Sorry for the spam, I should have given more thought to this before hitting reply). It actually seems to me that using a linear interpolation is not a good idea, since it will throw out a lot of information if you decrease the number of bins: to compute the value at time t, it will only use the c

Also: it seems like you are using values at the boundaries of the bins, while I think it would make more sense to compute interpolated values at the middle point of a bin. I'm not sure it'll make a big difference visually, but it may be more appropriate. -=- Olivier 2011/11/13 Olivier Delalleau

Just one thing: numpy.interp says it doesn't check that the x coordinates are increasing, so make sure it's the case. Assuming this is ok, I could still see how you may get some non-smooth behavior: this may be because your spike can either be split between two bins (which "dilutes" it somehow), o

Hi group, I have a rather simple problem, or so it would seem. However I cannot seem to find the right solution. Here's the problem: A Geiger counter measures counts in distinct time intervals. The time intervals are not of constant length. Imaging for example that the counter would always create
