 Mar 27 comment NonlinearModelFit for analytical data is giving errors It might also be better not to assign data to variables which you are also going to use as formal variables. Mar 27 reviewed Reopen How to generate a graph from a tetrahedral lattice Mar 25 comment What is the most efficient way to replace items in a list at periodic intervals? @march was about to write that... Mar 23 awarded Favorite Question Mar 23 comment Create a 3D face from the Shroud of Turin @vito they probably had a better picture than the one you provided.

It must fulfill specific conditions. Try for instance knots = {0, 0, 0, 0, .5, 1, 1, 1, 1}; Mar 22 comment Strange Error with Initialization within Animate @User18 It should be noted that SaveDefinitions can be dangerous: 6579644, 31998, 39631.

Mar 20 comment Closed form probability random walk will hit k >=1 times in n steps Indeed, I don't think my solution is correct, but I think your recursion equation is not correct either. Your c[n,k] is the probability to end up at +k after n steps, not the probability of having visited +k at least once. Mar 20 comment The Orbit and Perigee of the Flamsteed comet @J.M. However, "OrbitPath" works. Mar 20 comment Closed form probability random walk will hit k >=1 times in n steps 1 - Product[CDF[RandomWalkProcess[1/2][i], k - 1], {i, 0, n}] Mar 20 comment Wrong bearing between two GeoPositions compared to Google Earth In the calculation of blat there is an erroneous a term. This is not the cause of your problem, but wrong nevertheless. Mar 19 awarded Necromancer Mar 19 comment Strange Error with Initialization within Animate I'm afk at the moment. Have you tried AnimationRunning ->False? Mar 19 comment How to systematically approach when solving a large system of differential equations? I added a range for t and made all values integer or rational instead of real. And I have 10.4 Mar 19 comment How to systematically approach when solving a large system of differential equations? NDSolve gets you this figure. There are clear problems beyond t=0.06. Mar 19 comment Basic Syntax Question — Variables for a function By writing it this way the author is separating parameters from variables. Using Subscript is a big no-no in Mathematica programming (as Sektor's link indicates). While it is possible to use it, it leads to problems more often than not. Please resist the temptation to use it.
