GEN02
GEN02 — Transfers data from immediate pfields into a function table.
Initialization
size -- number of points in the table. Must be a power of 2 or a power-of-2 plus 1 (see f statement). The maximum tablesize is 16777216 (224) points.
v1, v2, v3, etc. -- values to be copied directly into the table space. The number of values is limited by the compile-time variable PMAX, which controls the maximum pfields (currently 1000). The values copied may include the table guard point; any table locations not filled will contain zeros.

If p4 (the GEN routine number is positive, the table will be post-normalized (rescaled to a maximum absolute value of 1 after generation). A negative p4 will cause rescaling to be skipped. You will usually want to use -2 with this GEN function, so that your values are not normalized. |
Examples
Here is an example of the GEN02 routine. It uses the files gen02.csd.
