Web1 Answer. Sorted by: 17. Let M = U Σ V be the singular value decomposition of M, then R = U V. If you want R to be a proper rotation (i.e. det R = 1) and U V is not, replace the singular vector u 3 associated with the smallest singular value of M with − u 3 in the U matrix. An appropriate reference for this answer is: WebSecondly, a general scheme for orthogonal matrix nearness problems under any unitarily invariant norm is addressed and the corresponding iterative algorithm is proposed. Thirdly, feature representation problems are formulated as certain forms of orthogonal matrix nearness, indicating a joint framework for learning low-dimensional features with closed …

"WebMatrix nearness problems are introduced in [13] where for a xed matrix A, the problem of nding the nearest member of some given class of matrices is addressed, where distance is measured in a matrix norm. The problem of approximating a matrix with a positive semide nite symmetric matrix is ubiq-uitous in scienti c computing, see e.g. [12{15]. " - Matrix nearness problems and applications
