table3

table3 — Accesses table values by direct indexing with cubic interpolation.

Description

Accesses table values by direct indexing with cubic interpolation.

Syntax

ares table3 andx, ifn [, ixmode] [, ixoff] [, iwrap]
ires table3 indx, ifn [, ixmode] [, ixoff] [, iwrap]
kres table3 kndx, ifn [, ixmode] [, ixoff] [, iwrap]

Initialization

ifn -- function table number.

ixmode (optional) -- index data mode. The default value is 0.

  • 0 = raw index

  • 1 = normalized (0 to 1)

ixoff (optional) -- amount by which index is to be offset. For a table with origin at center, use tablesize/2 (raw) or .5 (normalized). The default value is 0.

iwrap (optional) -- wraparound index flag. The default value is 0.

  • 0 = nowrap (index < 0 treated as index=0; index > tablesize sticks at index=size)

  • 1 = wraparound.

Performance

table3 is identical to tablei, except that it uses cubic interpolation. (New in Csound version 3.50).
