Hello all, There is a lot happening in my life right now and I am spread quite thin among the various projects that I take an interest in. In particular, I am thrilled to publicly announce on this list that Continuum Analytics has received DARPA funding (to the tune of at least $3 million)

Suppose I have two positive definite matrices, A and B. Is it possible to use U*D*U^T factorizations of these matrices to obtain a numerically stable result for their difference, A - B ? My application is the "UD" factorization method for the Kalman filter followed by the Rauch-Tung-Striebel s

[Numpy-discussion] required nose version.

2012-12-16 Thread Charles R Harris
Hi All, Looking at INSTALL.txt with an eye to updating it since we have dropped Python 2.4 -2.5 support, it looks like we could update the nose version also. The first version of nose to support Python 3 was 1.0, but I think 1.1 would better because of some bug fixes. IPython also requires nose 1.
