[Numpy-discussion] inverting and calculating eigenvalues for many small matrices

Hi, I am trying to find the eigenvalues and eigenvectors as well as the inverse for a large number of small matrices. The matrix size (MxM) will typically range from 2x2 to 8x8 at most. The number of matrices (N) can be from 100 up to a million or more. My current solution is to define "eig" and "i

[Numpy-discussion] Problem with ufunc of a numpy.ndarray derived class

Hi, I have a problem with the ufunc return type of a numpy.ndarray derived class. In fact, I subclass a numpy.ndarray using the tutorial : http://docs.scipy.org/doc/numpy/user/basics.subclassing.html But, for example, if I execute the "max" ufunc from my subclass, the return type differs from

Re: [Numpy-discussion] FloatingPointError: overflow encountered in multiply

I found and fixed the problem. I had performed a distance computation of all point to all points. My points included a query point and I needed to set its distance to something large. So I did distances[query_point] = 1e308; ts = distances / band_width; x = ts * ts and got the overflow, which makes
