nonlinearfitwithmaxiters

I upgraded my LabWindows from 6.0 to 2009. However I found that the NonLinearFitWithMaxIters function gave different result for the two versions. I haven't checked other functions yet. Any explanation for this? Thanks.

Also, I noticed that the calculation time is significantly longer for CVI 2009.

Hi,

there are a few issues regarding this function that were fixed in the 2009 release, see here: https://www.ni.com/en/support/documentation/bugs/10/archived--labwindows--cvi--2009-and-2009-sp1-kno...

Hi Jie,

My testing has shown that difference in this function can be tracked be tracked down to changes in the algorithm of the function made between between versions 7.1 and 8.0 of CVI.
