U can be written as U = e iH, where e indicates the matrix exponential, i is the imaginary unit, and H is a Hermitian matrix. For any nonnegative integer n, the set of all n × n unitary matrices with matrix multiplication forms a group, called the unitary group U(n). Any square matrix with unit Euclidean norm is the average of two unitary matrices.

An equivalent real-valued. INTRODUCTION In mathematics, a unitary matrix is an n by n complex matrix U satisfying the condition where , is the identity matrix in n dimensions and , A N × N unitary matrix can be written in the following form. Uij = aij + ibij. So, there are N2 of a's and N2 of b's, and 2N2 of parameters altogether.

Unitary group. In mathematics, the unitary group of degree n, denoted U (n), is the group of n×n unitary matrices, with the group operation that of matrix multiplication. The unitary group is a subgroup of the general linear group GL (n, C). In the simple case n = 1, the group U (1) corresponds to the circle group, consisting of all complex Unitary matrix definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation.

Parametrisation of unitary matrices 3467 These relations imply Dv=O, Du* = 0. (2.4b) If B and C are k x k matrices, U and V are unitary operators.Thus the B and C matrices are determined by the defect operators DA and DA* up to some isometries U and V which are much simpler operators. In order to find the last matrix block we shall use the following result.

Notice that if U happens to be a real matrix, , and the equation says --- that is, U is orthogonal. In other words, unitary is the complex analog of orthogonal.

A Unitary Matrix is a form of a complex square matrix in which its conjugate transpose is also its inverse. This means that a matrix is flipped over its diagonal row and the conjugate of its inverse is calculated. If the resulting output, called the conjugate transpose is equal to the inverse of the initial matrix, then it is unitary.

In other words, unitaryis the complex analog of orthogonal. By the same kind of argument I gave for orthogonal matrices, UU∗ = I implies U∗U = I — that is, U∗ is U−1. Proposition.

Unitary matrix. is a unitary matrix if its conjugate transpose is equal to its inverse , i.e., . When a unitary matrix is real, it becomes an orthogonal matrix, . The column (or row) vectors of a unitary matrix are orthonormal, i.e. they are both orthogonal and normalized:

In mathematics, a unitary matrix is an n by n complex matrix U satisfying the condition where, is the identity matrix in n dimensions and, is the conjugate transpose (also called the Hermitian adjoint) of U.

Thus, the off-diagonal entries must be $\sin\frac{\tilde\theta}{2}$ up to some … Unitary matrices - Ximera. A set of n vectors in C n is orthogonal if it is so with respect to the standard complex scalar product, and orthonormal if in addition each vector has norm 1. Similarly, one has the complex analogue of a matrix being orthogonal. A unitary matrix of order n is an n × n matrix [u ik] with complex entries such that the product of [u ik] and its conjugate transpose [ū ki] is the identity matrix E.The elements of a unitary matrix satisfy the relations.

An complex matrix is unitary if , or equivalently if . Just as orthogonal matrices are exactly those that preserve the dot product, we have 1.酉矩阵（unitary matrix）若n阶复数矩阵A满足则称A为酉矩阵,记之为A。其中,是A的共轭转置。2.性质如果A是酉矩阵1.=2.也是酉矩阵；3.det(A)=1;行列式determinant,方阵所对应的行列式充分条件是它的n个列向量是两两正交的单位向量。 Unitary matrix definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation.
