SVD module

Detailed Description

This module provides SVD decomposition for matrices (both real and complex). Two decomposition algorithms are provided:

• JacobiSVD implementing two-sided Jacobi iterations is numerically very accurate, fast for small matrices, but very slow for larger ones.
• BDCSVD implementing a recursive divide & conquer strategy on top of an upper-bidiagonalization which remains fast for large problems. These decompositions are accessible via the respective classes and following MatrixBase methods:
• MatrixBase::jacobiSvd()
• MatrixBase::bdcSvd()
