2 * OpenDocument <drawing> input and output
3 *
4 * This is an an entry in the extensions mechanism to begin to enable
5 * the inputting and outputting of OpenDocument Format (ODF) files from
6 * within Inkscape. Although the initial implementations will be very lossy
7 * do to the differences in the models of SVG and ODF, they will hopefully
8 * improve greatly with time. People should consider this to be a framework
9 * that can be continously upgraded for ever improving fidelity. Potential
10 * developers should especially look in preprocess() and writeTree() to see how
11 * the SVG tree is scanned, read, translated, and then written to ODF.

262 * Singular Value Decomposition.
263 * <P>
264 * For an m-by-n matrix A with m >= n, the singular value decomposition is
265 * an m-by-n orthogonal matrix U, an n-by-n diagonal matrix S, and
266 * an n-by-n orthogonal matrix V so that A = U*S*V'.
267 * <P>
268 * The singular values, sigma[k] = S[k][k], are ordered so that
269 * sigma[0] >= sigma[1] >= ... >= sigma[n-1].
270 * <P>
271 * The singular value decompostion always exists, so the constructor will
272 * never fail. The matrix condition number and the effective numerical
273 * rank can be computed from this decomposition.
