| Suppose I have the expression: c q u - i q x - c w y + e x y - e u z + i w z I'd like to be able to run FullSimplify or Simplify on it and get this: Det[{{a, b, c}, {d, e, f}, {g, h, i}}] One can argue that the evaluated form is... |
| I suspect the answer to this question is likely to be embarrassingly simple, but right now I'm at a loss as to why the following two examples behave so differently: Trying to replicate the FindRoot function behavior in Mathematica for solving a... |

| Trying to establish a connection to MS SQL Server 2014 - is it supported? The jTDS driver version is 1.3.1 /which appears to be the latest/ says the supported sql server versions are ... 2000,2005,2008,2012 without any mention to 2014. Has anyone... |
| Shouldn't the following two results be identical? /The documentation says LeastSquares works on both Array and SparseArray objects/ Could this be a bug in the function? ...or am I not using it properly? [mcode]With[{m = {{0.4472135954999579` -... |
| A relatively simple mathematical problem /not for me though/ Given is a sorted list of integers: a = {a1,a2,a3,...an}I need to find a subset b={b1,b2,b3...bm}such thatb2-b1=x b3-b2=x b4-b3=x ...Where x is... |
| I have defined this pattern: PPerson = Person[Name_String, Phone_String, Age_Real, Address_String]Thenp = Person["John", "xxx-xxxx", 34., "US"] MatchQ[p, PPerson] I'd like to be able to do the following: [code]Modify[p,... |
| This one should be fairly easy for any Mathematica programmer: I have GP = GeoPoint[Name_, {East_Real, North_Real}, Elev_Real]; GP // FullForm and need to get rid of al the patterns in order to use the expression on the rhs This... |
| $Version "9.0 for Microsoft Windows (64-bit) (January 25, 2013)" I have a line in my .nb file that reads comething like this:SyntaxInformation[myFunc] = {"ArgumentsPattern" -> {_, _}}; I tried placing it in both the private and public... |
| The routine is a working program that helps optimize disk usage by choosing which files to select for burning. Suppose you have a bunch of images that you want to burn to a disc with given capacity, for example a 4.3 Gb DVD. The total size of your... |
