Hi All,

I ran into magic squares (Matlab has a magic() built in function) and a curiosity light bulb went on in my bain, askin the following question:

"Can we use (large) magic squares to generate random numbers?"

I did a limit test (100 by 100 magic square matrix) and then manipulated the numbers:

1. Divide each element by the row/colum sum.

2. Discard the first few decimal digits using something like:

x = 100*x - fix(100*x) = frac(100*x)

I got 10,000 random numbers which may not be a whole lot of PC applications.

Any better approach to generate (and re-generate) batches of random numbers from magic squares?
