Detailed Description

The result of a singular value decomposition.

Objects of this type hold the results of a singular value decomposition (SVD) of an $m \times n$ matrix $A$, as returned by svd(). The SVD takes the form: $A = U \cdot \Sigma \cdot V'$. SVD objects contain d, which holds the singular values of $A$ (the diagonal of $\Sigma$) in descending order. Furthermore, depending on the options passed to svd(), they may hold some or all of the left singular vectors of $A$ in U and some or all of the right singular vectors of $A$ in Vt.
