-/**
- * @brief  Initialization function for the floating-point FIR interpolator.
- * @param[in,out] *S        points to an instance of the floating-point 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 was successful or ARM_MATH_LENGTH_ERROR if
- * the filter length <code>numTaps</code> is not a multiple of the interpolation factor <code>L</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[numTaps-2], ..., b[1], b[0]}
- * </pre>
- * The length of the filter <code>numTaps</code> must be a multiple of the interpolation factor <code>L</code>.
- * \par
- * <code>pState</code> points to the array of state variables.
- * <code>pState</code> is of length <code>(numTaps/L)+blockSize-1</code> words
- * where <code>blockSize</code> is the number of input samples processed by each call to <code>arm_fir_interpolate_f32()</code>.
