Hi Ben, Yes, this is more or less what I want to do. I want to apply this data in columns in a matrix, and insert the results to additional columns. I am not entirely aware of a good way of doing this.
e.g. take data from column B, apply normalisation, and feed output into column C Thanks, rcoder Ben Tupper wrote: > > > On Jul 15, 2008, at 8:16 AM, rcoder wrote: > >> >> Hi everyone, >> >> I want to score a set of data (-ve to +ve) using a 0-10 scale.
