Also, apparently I have the same problem as J. M -- I don't get pings because 3 alpha-numeric characters are necessary. So I see messages only if I catch them in the transcript
I'm trying to install Mathematica in the home folder on the university computer of a friend. The system administrator does not want it in /usr. Fine. Install went fine, also installed the scripts in the personal folder, added that folder to the path. Then the first thing was that the fonts didn't...
I looked at the “accept rate” of some of the site’s top users and found that it varies widely in the range 45%–100%. I was surprised with that, as it may be taken as an indicator that either:
hard questions don’t tend to get very good answers (let's assume that top users ask difficult questions...
Is there any algorithm that gives the compass direction and the size of a shadow given latitude, longitude, date and time?
also we have the size of object and the angle of object from ground plane
(Assuming we are an flat ground and that whatever the shadow falls from stands upright.)
@Heike yeah, there is no way you're going to answer another 95 questions over there. I'm only shy 30 upvotes, on the other hand. I've got the answers count needed.
Consider the following graph (source):
Is there any way to extract the data points from this image in a semi-automatic way? I have seen, and tried the methods suggested in this question, but they did not work, as most of the approaches there utilize color contrast to extract the data; I couldn...
@Eli I would give ImageLines a try for the axes as in the other question, and ImageCorrelate for the plot markers (which fortunately are all a uniform size and have distinctive shapes).
MorphologicalTransform shows some weird caching issues.
If I define some function f and do MorphologicalTransform[img, f], and then clear f and change the definition of f, MorphologicalTransform[img, f] still uses the old definition of f.
The only way I can get MorphologicalTransform to behave is to Remove f before redefining it.
It became customary among many users to abuse the quotation markup to indicate Mathematica output, like
Range[5]
{1, 2, 3, 4, 5}
I wonder whether it would be possible to create a MMA.SE specific markup, maybe something similar to the ==> used by the copy/paste palette, that would create...
The 3x+1, or Collatz problem remains open despite 70+ years of theoretical and computational work. Two key conjectures listed in Lagarias' recent book are the Finite Cycle Conjecture (FCC) and Divergent Trajectory Conjecture (DTC).
Instead of following the trajectories of individual numbers, con...
