"Find POTE = T/T[1]"

It doesn't seem to handle the case where the period is a fraction of an octave. For example, try this diaschismic mapping: [2, 2, 7, 15], 0, 1, -2, -8]]. We know the period is half an octave. Indeed,

T = [599.44659699 703.03185125]

Now POTE = T/T[1] gives

POTE = [1200. 1407.36176623]

Is this correct?

Besides, since I don't see a definition of TE generator, I don't know if it should be octave reduced, period reduced or left as is. Changing the basis definitely changes the result. Does TE generators specify a basis or whatever maps are accepted?

From my perspective, this seems more intuitive:

  • Find the TE octave: o = (T*V)1, that is, the first entry of T*V.
  • POTE = T/o

resulting in

POTE = [600. 703.68088312]
