ZGESVD Example

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

A = $\displaystyle \left(\vphantom{
\begin{array}{rrrrrr}
0.96 - 0.81i & -0.03 + 0...
....08 - 0.28i & 0.20 - 0.12i & -0.07 + 1.23i & 0.26 + 0.26i
\end{array} }\right.$$\displaystyle \begin{array}{rrrrrr}
0.96 - 0.81i & -0.03 + 0.96i & -0.91 + 2.0...
...i \\
1.08 - 0.28i & 0.20 - 0.12i & -0.07 + 1.23i & 0.26 + 0.26i
\end{array}$$\displaystyle \left.\vphantom{
\begin{array}{rrrrrr}
0.96 - 0.81i & -0.03 + 0...
....08 - 0.28i & 0.20 - 0.12i & -0.07 + 1.23i & 0.26 + 0.26i
\end{array} }\right)$,

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

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