-/**
- * @defgroup CmplxByCmplxMult Complex-by-Complex Multiplication
- *
- * Multiplies a complex vector by another complex vector and generates a complex result.
- * The data in the complex arrays is stored in an interleaved fashion
- * (real, imag, real, imag, ...).
- * The parameter <code>numSamples</code> represents the number of complex
- * samples processed. The complex arrays have a total of <code>2*numSamples</code>
- * real values.
- *
- * The underlying algorithm is used:
- *
- * <pre>
- * for(n=0; n<numSamples; n++) {
- * pDst[(2*n)+0] = pSrcA[(2*n)+0] * pSrcB[(2*n)+0] - pSrcA[(2*n)+1] * pSrcB[(2*n)+1];
- * pDst[(2*n)+1] = pSrcA[(2*n)+0] * pSrcB[(2*n)+1] + pSrcA[(2*n)+1] * pSrcB[(2*n)+0];
- * }
- * </pre>
- *
- * There are separate functions for floating-point, Q15, and Q31 data types.
