<p>New page: A '''unitary matrix''' is a complex matrix <math>U</math> satisfying the condition :<math>U^\dagger U = UU^\dagger = I_n\,</math> where <math>I</math> is the <a href="/SklogWiki/index.php/Identity_matrix" title="Identity matrix">identity matrix</a>...</p>
<p><b>New page</b></p><div>A '''unitary matrix''' is a complex matrix <math>U</math> satisfying the condition<br />
<br />
:<math>U^\dagger U = UU^\dagger = I_n\,</math> <br />
<br />
where <math>I</math> is the [[identity matrix]] and <math>U^\dagger</math> is the conjugate transpose (also called the Hermitian adjoint) of <math>U</math>. Note this condition says that a matrix <math>U</math> is unitary if and only if it has an [[inverse matrix|inverse]] which is equal to its conjugate transpose <math>U^\dagger \,</math><br />
<br />
:<math>U^{-1} = U^\dagger.</math><br />
<br />
A unitary matrix in which all entries are real is called an orthogonal matrix.<br />
