The VBA code for the drag function fit is in the workbook, I just checked it. You have to switch on the developer tab in Excel to get access to it.
Sorry for the confusion, you are right about that code, what I meant is the VBA code of
BfX main routines.
I'm not skilled with Excel programming, but I do well in Visual Basic, and while VBA is not the same it's quie easy to port.
My goal is to make a public library of
BfX functions on a higher language, to share with
BfX community.
My idea also, is to port that code to other languages (C#, Java) as well as long as others are interested.
Well, just an idea that could make sense for the members.
