pow
pow — Computes one argument to the power of another argument.
Initialization
inorm (optional, default=1) -- The number to divide the result (default to 1). This is especially useful if you are doing powers of a- or k- signals where samples out of range are extremely common!
Performance
aarg, iarg, karg -- the base.
ipow, kpow -- the exponent.
