It's probably a bit of a newbie question but I'm new to SMath (and matrices !) so any help would be appreciated. I want to perform calculations on the data in matrix BODY. I've done this in BODY2 as a workaround but I'd like to find a way of doing it so I don't have to edit BODY2 everytime I add or delete a row. Any help / guidance would be appreciated Peter TableRegion_Test.sm (11kb) downloaded 13 time(s).

I don't use much this feature for collecting data, but can demonstrate how to fill. By same token, the attached "matrix Treasury might help in real "Matrix maths".
