DF * (N-1) + P(see below).
Single-precision real filter vector.
Single-precision complex output vector.
Length of output vector
Length of filter vector
Performs finite impulse response (FIR) filtering at selected positions of the input vector
C, with the filter
F, using the decimation factor
DF. Results are left in the output vector
This function can run in place, but
C cannot be in place with
This function’s operation is indicated by the following pseudocode:
