## ptable3

ptable3 — Accesses table values by direct indexing with cubic interpolation.

## Description

Accesses table values by direct indexing with cubic interpolation.

## Syntax

    ares ptable3 andx, ifn [, ixmode] [, ixoff] [, iwrap]

    ires ptable3 indx, ifn [, ixmode] [, ixoff] [, iwrap]

    kres ptable3 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

ptable3 is identical to table3, except that it uses does not require the table to have a power of two size.
