You can get only the first three using data[[All, 1 ;; 3]]

Do you need the symbolic solution or a numerical one will suffice your need?

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!

comment Doing local FFT on huge 3D vector data cell mesh and visualizing it spatially?
@OleksandrR. You are right I checked BinaryReadList with Real32 will probably not be able to read binary data in the attached file? We need to use other library...
