The 'seq' command simply makes a vector [2,4,6,8,10] and the 'colunmod'
function is what I am looking for i.e. a function that will undo/unwrap
the function mod(x,y). I have looked for this function on the net as
you suggested (Martin's IDL 11 online libraries) but I have yet to find
it... Can you be more specific regarding which library or where I should
look?

Indeed, I only need the dim 1 case.

Thanks!
