ZGESDD Example

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

A = $\displaystyle \left(\vphantom{
\begin{array}{rrrrrr}
0.96 + 0.81i & -0.98 - 1...
....11 - 0.60i & 0.22 + 0.20i &
1.47 - 1.59i & 0.26 - 0.26i
\end{array} }\right.$$\displaystyle \begin{array}{rrrrrr}
0.96 + 0.81i & -0.98 - 1.98i & 0.62 + 0.46...
....56i & -1.11 - 0.60i & 0.22 + 0.20i &
1.47 - 1.59i & 0.26 - 0.26i
\end{array}$$\displaystyle \left.\vphantom{
\begin{array}{rrrrrr}
0.96 + 0.81i & -0.98 - 1...
....11 - 0.60i & 0.22 + 0.20i &
1.47 - 1.59i & 0.26 - 0.26i
\end{array} }\right)$,

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

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