Difference equation, 2 poles, 2 zeros; single precision.

Single-precision real input vector.
5 single-precision inputs (filter coefficients), with stride 1.
Single-precision real output vector.
Number of new output elements to produce.
This function creates
N new values in output vector
C, beginning with its third element. It performs two-pole two-zero recursive filtering on input vector
A, which must contain at least
N + 2 values;
C must also contain at least
N + 2 values. Since the computation is recursive, the first two elements in
C must be initialized prior to calling this function. This function can only be done out of place.
