ZGESDD Example

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

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

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.
