Hi All, The numpy buildbot has been down for a while now, or maybe I just missed some time when it was up. Is this a known problem? Chuck ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussio

[Numpy-discussion] Percentiles and Box Plots

I have from about 90 to 600 points of different data sets that I would like to find the 10th and 90th percentile for. Does numpy have a function for that, or any other percentile points? Is there a method for getting at the Box Plot quartiles, and ranges. I think that's the simplest set for Bo

For the case where all the eigenvalues are simple, this works for me: In [1]: import numpy as np In [2]: a = np.array([[1.0, 2.0, 3.0],[2.0, 3.0, 0.0], [3.0, 0.0, 4.0]]) In [3]: eval, evec = np.linalg.eig(a) In [4]: eval Out[4]: array([-1.51690942, 6.24391817, 3.27299125]) In [5]: a2 = np.do

Re: [Numpy-discussion] linalg.eig getting the original matrix back ?

numpy.linalg.eig guarantees to return right eigenvectors. evec is not necessarily an orthonormal matrix when there are eigenvalues with multiplicity >1. For symmetrical matrices you'll have mutually orthogonal eigenspaces but each eigenspace might be spanned by vectors that are not orthogonal to ea

I had a problem because linal.eig doesn't rebuild the original matrix, linalg.eigh does, see script below Whats the trick with linalg.eig to get the original (or the inverse) back ? None of my variations on the formulas worked. Thanks, Josef import numpy as np import scipy as sp import scipy.li
