| Just in case, if you have not seen this. There is a quite [detailed list of things][1] you can do with Wolfram|Alpha PRO. You should take a look if you haven't yet. Note, one of the features mentioned on that page is [Wolfram Problem Generator][2]... |
| Why is the current represented as a function vs. a given value? I am trying to solve the H-H equations that he did in this simulation, and have no problems execpt for understanding why Current is not a given value. I want someone to go to the... |
| use something like: [mcode]data= Select[data,#>0.5&] data= Select[data,0.3 |
| I just realized that your data have 500,000 points and most of them cary no meaningful information because of almost zero "background" intensity. I would suggest filtering data based on higher intensity - and plotting only those. Something like the... |
| Thanks Vitaliy for gathering all this info. I didn't expect Wolfram Research to pay much attention to the page since I figured you guys see more examples of how powerful Mathematica can be than most people. I thought maybe I would see a message from... |
| Since there is such a huge amount of sectors in total you can reduce that by a fair bit and still get a decent result: [mcode]sectorsPerRing[r_] := Floor[5 r]; m2 = MapIndexed[ Mean /@ Partition[#, Ceiling[dim[[2]]/sectorsPerRing@First@#2], ... |
| Take a look at the following discussion thread on stackexchange to get a sense of how to approach step-by-step differentiation in Mathematica... ... |
| There are a number of questions about this on Mathematica.SE. Here are two you may be interested in: [list]... |
