Webb28 okt. 2014 · SVD_LAPACK provides a SVD routine based on ZGESDD, which is not supported as Matlab's built-in function, at least, explicitly. Lapack, a fortran computational library, has two different subroutines. for the Singular Value Decompostion (SVD): xGESVD and xGESDD. xGESVD is based on an implicit QR iteration and xGESDD … Webb我有一个矩阵B，它是正方形且密集的，还有一个矩阵A，它是矩形且稀疏的.. 有没有一种方法可以有效地计算积 B^-1 * A? 到目前为止，我使用(在 numpy 中). tmp = B.inv() return tmp * A 我相信，这使我们了解了 A 的稀疏性.我在考虑使用稀疏方法numpy.sparse.linalg.spsolve，但这需要稀疏的 B，而不是 A.
