4.5 Polynomial interpolation (POLY, POLYPATH, PO, PL)
Comment
; Polynomial interpolation on
; Mixed data for the axes
; No PL programmed; PL=1 applies
; Polynomial interpolation off
New polynomial syntax
Axis identifier=PO(.. , ..)
PHI=PO(.. , ..)
PSI=PO(.. , ..)
THT=PO(.. , ..)
PO(.. , ..)
variable=PO IC(.. , ..)
