I'm writing unit tests for a module that contains matrices. I was surprised that these are True:
>> import numpy.matlib as mp >> x = mp.matrix([[mp.nan]]) >> x.any() True >> x.all() True My use case is (x == y).all() where x and y are the same matrix except that x contains one NaN. Certianly x and y are not equal. >> x = mp.asmatrix(range(4)).reshape(2,2) >> y = mp.asmatrix(range(4)).reshape(2,2) >> x[0,0] = mp.nan >> (x == y).all() True _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
