In [3]: sp.gmres(np.eye(5,5),np.zeros(5)) /home/juser/.local/lib/python2.7/site-packages/numpy/core/fromnumeric.py:2499: VisibleDeprecationWarning: ‘rank‘ is deprecated; use the ‘ndim‘ attribute or function instead. To find the rank of a matrix see ‘numpy.linalg.matrix rank‘. VisibleDeprecationWarning) Out[3]: ([0.0,0.0,0.0,0.0,0.0],0)
