) -> Type
@brief Initialization function for the Q15 FIR interpolator.
@param[in,out] S points to an instance of the Q15 FIR interpolator structure.
@param[in] L upsample factor.
@param[in] numTaps number of filter coefficients in the filter.
@param[in] pCoeffs points to the filter coefficient buffer.
@param[in] pState points to the state buffer.
@param[in] blockSize number of input samples to process per call.
@return The function returns ARM_MATH_SUCCESS if initialization is successful or ARM_MATH_LENGTH_ERROR if
the filter length numTaps
is not a multiple of the interpolation factor L
.
