Hi Eddy, >1) Did you introduce long double because your > algorithms need a higher accuracy ? > I introduced them because I demanded highest accuracy from the start, not because I had proof Double_t wasn't enough. > If so, > a.

But the Windows results are *really* different and non-sensical, so I can't just push ahead. >2) Are you seeing differences between Windows and > linux using TMatrix . That should not be the case. > I made my 'port to Windows, omitting the TMatrixQ because of statments like yours. Now I see differences. All the rest of the code is as close to the same as possible. Once I finish implementing I will see if the results are then the same. If so, that will be the example you want, but it's proprietary and I can't provide it. If it is still not the same, then I'll look elsewhere. In the event I can finger the accuracy as a source of my problem, I'm sure I can put together a public example that highlights the problem. But not today. - J -- Dr. John Krane jkrane@netzero.com
