SUMMARY
The discussion focuses on the relationship between the Hermitian inner product of two complex vectors, denoted as \( x^{H}y \), and the angle \( \theta \) between them. It establishes that the angle in complex space is defined similarly to that in real space, utilizing the real part of the complex inner product to derive the cosine of the angle. The conclusion emphasizes that the cosine of the angle can be expressed as the normalized Hermitian inner product of the vectors.
