Singular Value Decomposition
The singular value decomposition is a factorization of a matrix
into
. A vector
is first rotated by an angle β via
, then
is scaled by a diagonal matrix
to form
. Finally the vector
is rotated by an angle ω to form
.

DETAILS
Note that U and V are orthogonal matrices and thus do not alter the length of the vectors. In 2D the diagonal matrix Σ has the form
here
are the singular values of the matrix.
