WEBLast Updated : 02 Jan, 2024. Unitary Matrices are defined as square matrices of complex numbers such that the product of the conjugate transpose of a unitary matrix, with unitary matrix itself, gives an identity matrix. Matrices are defined as rectangular arrays in which numbers are arranged in rows and columns.

What is a Unitary matrix? (With examples and its properties)
https://www.algebrapracticeproblems.com:443/unitary-matrix/
WEBA unitary matrix is a complex matrix that multiplied by its conjugate transpose is equal to the identity matrix, thus, the conjugate transpose of a unitary matrix is also its inverse. That is, the following condition is met: Where U is a unitary matrix and U H its conjugate transpose. See: complex conjugate transpose of a matrix.

WEBDec 28, 2021 · Unitary Matrix Definition. A unitary matrix is a matrix whose inverse is equal to the conjugate transpose. Conjugate transpose is referred to as the Hermitian matrix. The unitary matrices may also be non-square matrices but the matrices have orthonormal columns. The unitary matrix is denoted by U.
