floating point, step forward issue, Manipulate Appearance -> "Labeled" Consider the following: Manipulate[Null, {{a, -0.1, "a"}, -0.1, 0.1, 0.1, Appearance -> "Labeled"}] Now click on the little "+" button at the end of the slider near the number ".1" to open the animation controls. Now click on the "play" button, You should see nothing too exciting, just a sequence of num... 31 Mar 2010 06:31
0/1 knapsack-like minimalization problem and file system access Given the files in a directory, by what method can I receive the list of the files that in size is closest to, but not larger than, an arbitrary x value, given in bytes? Each file can be listed at most once. The file names and their respective sizes must be read in by Mathematica. (The directory contains files ... 31 Mar 2010 06:31
if with two conditions Hi all, Is there a way to build an if statement with two conditions such as: if[a>b and a>0,...]. If there is, could you let me know the syntax? Thanks nt ... 1 Apr 2010 07:53
priorities between @, @@ and // Hello all, Just a quick question : what are the priority between all those operators ? I mean : - what is f@x//g ? Is it f[g[x]] or g[f[x]] - what is f@@{a,b}[[2]] ? Is it f[b] or (f[a,b])[[2]] You see what I mean... What are the rules for the priority of all those operators ? TIA :) ... 30 Mar 2010 06:07
Resolution Time Study Hello Mathematica Community I've made a strange observation when using Mathematica 7 and Mathematica 5.1. I thought that Mathematica 7 is more performant than Mathematica 5.1 but when trying to solve the same system of equations and inequalities by the function Reduce[] , Mathematica 7 has spent 4794.03 seconds w... 1 Apr 2010 07:53

quartic equation Hi, I am totally unexperienced in MATHEMATICA, and I am looking for some advice. I need to solve a quartic equation symbolically, that is to factor a fourth order polynomial given in the power base. The coefficients of the polynomial are complicated expressions of a number of parameters, and I need to obtain ... 30 Mar 2010 06:07
ParametricPlot3D - plane appears contracted in some directions Consider following simple piece of code which should represent plane determined by two vectors: ******* Code Start ********** vector1 = {1, 2, 3} vector2 = {2, 3, 4} ParametricPlot3D[{u vector1 + v vector2}, {u, -10, 10}, {v, -10, 10}] ******* Code End ************ Question: Why with this code I get some k... 9 Apr 2010 04:31
Can one have different Coloring to show which local symbols are Am 27.03.2010 11:11, schrieb Nasser M. Abbasi: Hello; Many times when I write some module, I add local symbols, then later I might change the code and those symbols will no longer be used. For example f[x_]:=Module[{a,b},... a=...; ....] Suppose that 'a' is still used, but 'b' is not... 30 Mar 2010 06:07 |
