-/**
- * @defgroup cmplx_dot_prod Complex Dot Product
- *
- * Computes the dot product of two complex vectors.
- * The vectors are multiplied element-by-element and then summed.
- *
- * The <code>pSrcA</code> points to the first complex input vector and
- * <code>pSrcB</code> points to the second complex input vector.
- * <code>numSamples</code> specifies the number of complex samples
- * and the data in each array is stored in an interleaved fashion
- * (real, imag, real, imag, ...).
- * Each array has a total of <code>2*numSamples</code> values.
- *
- * The underlying algorithm is used:
- * <pre>
- * realResult=0;
- * imagResult=0;
- * for(n=0; n<numSamples; n++) {
- * realResult += pSrcA[(2*n)+0]*pSrcB[(2*n)+0] - pSrcA[(2*n)+1]*pSrcB[(2*n)+1];
- * imagResult += 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.
