comment Are there any functions that can determine the disorder between two lists?
You can give a try with HammingDistance[dj11,Union[dj11]]...

Before an one liner question you better search the site for similar questions. Check here mathematica.stackexchange.com/questions/2537/…

comment Speeding up a numerical constrained quadratic optimization
@Mechanicalsnail can you give us the objective formulation explicitly in your code. Then one may give the problem a better try.

comment Using NDSolve for Integro-Differential Equations
@ruebenko Actually in this way too the 1/0^.5 type error occurs internally triggering as a result NDSolve::icfail. Hope you find a way out..

comment How to find major color in a picture?
Should not it be Graphics[{#, Disk[]}] & /@ DominantColors[img, 4]? The answer as it is gives error in Mathematica 9.0.1. Anyways colors are completely different also from what you have got here.

comment 1D Euler Equations
I have edited your closed question. You are raising correct issues here but you need to present the problem at hand in a right manner. Best of luck in future!

comment Solve equations real and imaginary part separately
The way you defined the equations you can only expect trivial solutions. Try to check eq = (# == 0) & /@ (matrix . vector);Solve[eq, vector, Complexes]. Also be careful with the fact that initiating symbols with capital letters are avoided in Mathematica.

@ruebenko any chance in future for NDSolve to solve Navier-Stokes out of the box..?

comment Trying to use NDSolve to solve Blasius equation
You need f'[Infinity] == 1.0 but still error will occur with this Infinity I guess!

@Peter you can initiate the subgraph by assigning zero transition probability to all the complimentary edges in $G/S$

@thewanderer as Mark suggested one of the best papers on this topic is by Keith Briggs named "A precise calculation of the Feigenbaum constants Mathematics of Computation". You will find it here

comment How to find the index of a square matrix in Mathematica quickly?
@Szabolcs try testing your code with A={{1, 1, -1, 2}, {-1, 1, 0, 0}, {0, 1, -1, 2}, {1, 2, -1, 0}}. In my machine the kernel keeps on running....

comment Why the difference?
I guess he means this 1 + \!\( \*UnderoverscriptBox[\(\[Sum]\), \(n = 0\), \(\[Infinity]\)]\( \*UnderoverscriptBox[\(\[Sum]\), \(k = n\), \(\[Infinity]\)] \*FractionBox[\(1\), \(\((k + 1)\) \(k!\)\)]\)\). This by the way does not converge in Mathematica 9 and in place of 1 + e - Cosh[1] returns the input unchanged. The Sum version does converge to $\mathrm e$.

comment build and estimate a time series process
@Verbeia Not my ordinary neural net but all credit goes to proper keyword search in Google! However if you change AppendRows[a,b] with Join[a,b,2] and ZeorMatrix using ConstantArray you will be left with properly using the new version 9 ARMAProcess to replace your ARMAList. Then we can have a nice post here from you. Looking forward to it!
