Hi,

Rc can have any number of columns and I want to subtract one column (xc, xy...) from that.

Is this only possible with a loop, or is there a more elegant way?

It seems that you should write Rc: L-xc where xc is the vector of coordinates of the reference point. But you better attach an sm file and a more comprehensible description of what you want. I don't see a matrix with multiple columns in your example.

Hi Martin, here is the worksheet.
Rc should be calculated automatically depending on the number of forces entered.
