[Numpy-discussion] Inaccuracy in documentation of np.linalg.pinv

2011-03-08 Thread Hao Xiong
I think the documentation for np.linalg.pinv contains some inaccuracies. Most importantly, Moore-Penrose is not defined by the solution to the least-square problem. It was defined by the unique solution to 4 equations. Since SVD can be easily shown to satisfy the same 4 equations, it is the Moor
