Iterations in Mathematica [closed]

this is probably a very easy question for all of you.

I have a stochastic Mathematica code (not important what it's exactly) which gives me a number at the end. Now I want Mathematica to run this code 1000 times and put all the numbers into a list.

I tried by using the command While, but it gives for all of the thousand iterations the same number back.

How can I do this?

Edit: Perhaps it's better to show you the code:

XUJ = dataRe[χFF]["Values"] + I dataIm[χFF]["Values"];
XUJB = dataRe[χBB]["Values"] + I dataIm[χBB]["Values"];
PF[W_] = Δu/(2 Pi) (1 + 2 Re[uj.XUJ]);
PB[W_] = Δu/(2 Pi) (1 + 2 Re[uj.XUJB]);
dataLR = Transpose[{Table[W, {W, -((7 π)/10) + 2 Pi/10, (7 π)/10 - 2 Pi/10, Pi/10}],
Log[Table[PF[W], {W, -((7 π)/10) + 2 Pi/10, (7 π)/10 - 2 Pi/10,
Pi/10}]/Reverse[Table[PB[
W], {W, -((7 π)/10) + 2 Pi/10, (7 π)/10 - 2 Pi/10,
Pi/10}]]]}];

Last[LinearModelFit[Re[dataLR], x, x]["BestFit"]]/x


dataRe and dataIm generate the set of random numbers. Each time I evaluate now this cell I get a different number as it should be. I'm not sure how to implement this now into the Table command.

• Probably you are storing the value to the same variable? Considering storing it an array. Use ConstantArray to pre-initialize the array for speed. It's difficult to say without MWE. – Saurav Nov 27 '15 at 16:33
• Consider r := RandomReal[]; Table[r, {20}]. – J. M. is away Nov 27 '15 at 16:42
