Eigen::Matrix< complex_return_t< scalar_type_t< M > >, -1, -1 > stan::math::complex_schur_decompose_u ( const M &  m )

inline

Return the unitary matrix of the complex Schur decomposition of the specified square matrix.

The complex Schur decomposition of a square matrix A produces a complex unitary matrix U and a complex upper-triangular Schur form matrix T such that A = U * T * inv(U). Further, the unitary matrix's inverse is equal to its conjugate transpose, inv(U) = U*, where U*(i, j) = conj(U(j, i))

Template Parameters

M	type of matrix

Parameters

m	real matrix to decompose

Returns

complex unitary matrix of the complex Schur decomposition of the specified matrix
