ftmorf
ftmorf — Morphs between multiple ftables as specified in a list.
Description
Uses an index into a table of ftable numbers to morph between adjacent tables in the list.This morphed function is written into the table referenced by iresfn on every k-cycle.
Initialization
iftfn -- The table containing the numbers of any existing tables which are used for the morphing.
iresfn -- Table number of the morphed function
The length of all the tables in iftfn must equal the length of iresfn.
Performance
kftndx -- the index into the iftfn table.
If iftfn contains (6, 4, 6, 8, 7, 4):
-
kftndx=4 will write the contents of f7 into iresfn.
-
kftndx=4.5 will write the average of the contents of f7 and f4 into iresfn.

|
iresfn is only updated if the morfing index changes it's value, if kftindx is static, no writing to iresfn will occur. |
