AFAIK, a build-in function is (still) missing. However you might use a singular value decomposition to compute the numerical rank of a matrix. See e.g. http://osdir.com/ml/python.numeric.general/2006-02/msg00154.html Nils _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
