Hi all, 

I am making an excel spreadsheet to do a helmert's transformation. This basically mimics the old Helmerts program for the HP48. 

What I am lacking is the "Set scale to 1" function, which would be valuable.  Unfortunately, my knowledge of the mathematics is lacking, and I uncertain how this step is done. Most of the hemerts research i have uncovered involves graphing it in excel and is not specific to surveying.

If anyone is willing to give it a look, I can provide the spreadsheet and the sample data.
