I know this could be done just by creating a new variable by simply typing the new vaules in as shown in (h), but the data set I have is very much larger than the example shown here. > > help ISMEMBER > use the last column of g as one of its input and use the output to logically index into g. > > hth > Jos
Right so I would create a variable from (g) using the last column:a=g(:,2); and use this as an input and use (f) as an output. How would I then logically index this into (g)?
