This may not be of immediate help, but you might want to keep it in the back of your mind. Try and find an old math pack manual for an HP67 or 97 hand calculator. They had a series of matrix inversion programs that could be keyed into a calculator. The nice thing about the manuals was that they gave all the math (background as well as step by step) without any fancy functions. (for those who remember, the code had to be less than 200 lines long). I still use some of their methods today. s. figuers ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
