-/**
- * @brief Initialization function for the floating-point FIR decimator.
- * @param[in,out] *S points to an instance of the floating-point FIR decimator structure.
- * @param[in] numTaps number of coefficients in the filter.
- * @param[in] M decimation factor.
- * @param[in] *pCoeffs points to the filter coefficients.
- * @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 was successful or ARM_MATH_LENGTH_ERROR if
- * <code>blockSize</code> is not a multiple of <code>M</code>.
- *
- * <b>Description:</b>
- * \par
- * <code>pCoeffs</code> points to the array of filter coefficients stored in time reversed order:
- * <pre>
- * {b[numTaps-1], b[numTaps-2], b[N-2], ..., b[1], b[0]}
- * </pre>
- * \par
- * <code>pState</code> points to the array of state variables.
- * <code>pState</code> is of length <code>numTaps+blockSize-1</code> words where <code>blockSize</code> is the number of input samples passed to <code>arm_fir_decimate_f32()</code>.
- * <code>M</code> is the decimation factor.
