- * @defgroup cmplx_mag Complex Magnitude
- *
- * Computes the magnitude of the elements of a complex data vector.
- *
- * The <code>pSrc</code> points to the source data and
- * <code>pDst</code> points to the where the result should be written.
- * <code>numSamples</code> specifies the number of complex samples
- * in the input array and the data is stored in an interleaved fashion
- * (real, imag, real, imag, ...).
- * The input array has a total of <code>2*numSamples</code> values;
- * the output array has a total of <code>numSamples</code> values.
- * The underlying algorithm is used:
- *
- * <pre>
- * for(n=0; n<numSamples; n++) {
- * pDst[n] = sqrt(pSrc[(2*n)+0]^2 + pSrc[(2*n)+1]^2);
- * }
- * </pre>
- *
- * There are separate functions for floating-point, Q15, and Q31 data types.
