# unitary matrices

## Summary

Unitary matrices are the complex analogues of orthogonal matrices.

## Context

This concept has the prerequisites:

- complex vectors and matrices (Unitary matrices are a kind of complex matrix.)
- orthonormal bases (Unitary matrices are the complex analogue of orthogonal matrices.)
- eigenvalues and eigenvectors (Unitary matrices are characterized in terms of the eigenvalues having unit norm.)
