- * @brief Initialization function for floating-point normalized LMS filter.
- * @param[in] *S points to an instance of the floating-point LMS filter structure.
- * @param[in] numTaps number of filter coefficients.
- * @param[in] *pCoeffs points to coefficient buffer.
- * @param[in] *pState points to state buffer.
- * @param[in] mu step size that controls filter coefficient updates.
- * @param[in] blockSize number of samples to process.
- * @return none.
- *
- * \par Description:
- * <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>
- * The initial filter coefficients serve as a starting point for the adaptive filter.
- * <code>pState</code> points to an array of length <code>numTaps+blockSize-1</code> samples,
- * where <code>blockSize</code> is the number of input samples processed by each call to <code>arm_lms_norm_f32()</code>.
