Hello all: Finally, I found my home after a long lost search for the right stuff in LabVIEW! My first post is concerned with an error since the days of LV6.1 and seemed to be still haunting? Anyway, I keep getting an Error 1050 on my notebook with LV8.5.1 and with Matlab 2007b running on Vista Basic. Anyone has tips for a fix? Tried Sys Exec with invocation matlab -regserver and matlab -automation but LV complains can't execute script? I worked long and hard using an equivalent MathScript - but 3D vector manipulations is never permitted or is not totally possible even for the latest MathScript corrections done on LV 8.5.1. Help will be appreciated.
