Here\'s what I have. RandomChoice[{.5, .5} -> {Heads, Tails}, 3] then I write RandomChoice[{.5, .5} -> {Heads, Tails}, 5]
I spend a lot of time looking at larger matric开发者_如何学编程es (10x10, 20x20, etc) which usually have some structure, but it is difficult to quickly determine the structure of them as they get larg
I have to minimize a bunch of functions of n variables that can take values from an integer range. The functions have the general form:
Is there a way to make a minor modification of the default appearance of cells in the current Notebook without specifying the a开发者_JAVA技巧ll set of options?
I just spent a couple of hours trying to convert some old code that uses Mathematica 7\'s GraphPlot to use the new Mathematica 8 Graph functions. It seemed sensible since the new graph drawing is much
I have a set of coupled equations for the variables H, W, P, & T (below) that I need to non-dimensionalize. Is there a way of achieving this in Mathematica as doing it manually is proving difficul
Is there any way to force Mathematica to treat subscripted variables independently of their unsubscripted counterparts? More specifical开发者_如何学JAVAly. Say, I have the following definitions:
Is there a way in mathematica to have variable coefficients for NDSolve? I need to vary the coefficient values and create multiple graphs, but I cannot figure out a way to do it short of reentering th
Let S be a vector with unique elements, and s a subset of it, also with unique elements; e.g., S={1,2,3,4,5,6} and s={1,3,4,6}. Now given another vector c={7,8,9,7}, how can I create a vector C=[7,0,8
I\'d like to implement an operator f that commutes with differentiation D. Unprotect[D]; D[f[y___], x] := f[D[y, x]];
