DGESVD Example

To find the singular values and left and right singular vectors of the 6 by 4 matrix

A = $$\left(\vphantom{ \begin{array}{rrrr} 2.27 & -1.54 & 1.15 & -1.9... ...5 & 2.93 & -1.45 & 2.30 \\ 0.62 & -7.39 & 1.03 & -2.57 \end{array} }\right.$$$$\begin{array}{rrrr} 2.27 & -1.54 & 1.15 & -1.94 \\ 0.28 & -1.... ...\ -2.35 & 2.93 & -1.45 & 2.30 \\ 0.62 & -7.39 & 1.03 & -2.57 \end{array}$$$$\left.\vphantom{ \begin{array}{rrrr} 2.27 & -1.54 & 1.15 & -1.9... ...5 & 2.93 & -1.45 & 2.30 \\ 0.62 & -7.39 & 1.03 & -2.57 \end{array} }\right)$$,

together with approximate error bounds for the computed singular values and vectors.

The example program for DGESDD illustrates finding a singular value decomposition for the case m$\le$n.
