 Apr14 comment Does RunProcess work on Chinese Windows? maybe it's confusing it with DueProcess which would explain the $Failed (runs away) Apr6 comment How to make the computer consider two numbers equal up to a certain precision @rasher Moderators cannot change votes. You can make a dummy edit, reverse your vote and then undo the edit within the minute. (there will be a note in the history that you edited the post, but the contents will remain the same) Mar14 comment Performing analysis of data extracted from an SQL database If out is your expression w/o TableForm, then Evaluate[Symbol /@ First@out] = Transpose@Rest@out should work. This doesn't have anything to do with SQL queries though... Mar14 comment How to make a notebook that will be window maximized when open? I think you accidentally posted the same answer in two places Mar11 comment How to implement the dual Lagrange? It's open now @SjoerdC.deVries Mar9 comment Simulation of the semicircle Wigner Theorem What is your question? Mar8 comment Is Daylight Savings Time accounted for when using AbsoluteTime[]? This is the first thing mentioned in the documentation — "AbsoluteTime[] uses whatever date and time have been set on your computer system. It performs no corrections for time zones, daylight saving time, etc. " Mar6 comment Two identical functions give different answers This should probably just be a comment... Feb28 comment Diagonal minors of matrix "Since I am going to calculate the minors of big matrices and I only need to know the diagonal elements, is there a way just to calculate the diagonal elements in minor matrix?" — Surely, performance is an issue here. Feb10 comment Convex optimization @DanielLichtblau The remark included the clause following it — "and enforce sparsity". NMinimize handles$\ell_1$minimization fine. In compressive sensing/sparse theory, one wishes to solve an$\ell_0$minimization problem, but because that is NP-hard, you do$\ell_p,\ 0 2] after you initialize the package. You'd call it as {p, f} = pmtm[data, tapers, n, fs]. Jan7 comment Apply ColorFunction to an Image @DJJ I think this is what you're looking for: mathematica.stackexchange.com/a/67217/5 The question might even be a duplicate. Jan7 comment InterpolatingFunction used to work with mathematic 7 but not working with mathematica 10 Jan4 comment Speed up replacement using Rule Dispatch Associtation I'm not surprised. It's not unconceivable that Transpose[DD1].DD1 is more complex (in terms of leaf count and computations involved) than just DD1. What I said in my previous two comments was that you should go back to the drawing board and see if you can use mathematics to simplify the problem before throwing it to Mathematica. Since we don't know the origins of your problem or how you arrive at kappa`, we cannot help you there (nor is this necessarily the site for that).
