2 * OpenDocument <drawing> input and output

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.

237 * Singular Value Decomposition.
238 * <P>
239 * For an m-by-n matrix A with m >= n, the singular value decomposition is
240 * an m-by-n orthogonal matrix U, an n-by-n diagonal matrix S, and
241 * an n-by-n orthogonal matrix V so that A = U*S*V'.
242 * <P>
243 * The singular values, sigma[k] = S[k][k], are ordered so that
244 * sigma[0] >= sigma[1] >= ... >= sigma[n-1].
245 * <P>
246 * The singular value decompostion always exists, so the constructor will
247 * never fail. The matrix condition number and the effective numerical
248 * rank can be computed from this decomposition.
