For example linalg.signm(a) results in

AttributeError: 'module' object has no attribute 'signm'
>>> a
array([[ 29.2, -24.2,  69.5,  49.8,   7. ],
        [ -9.2,   5.2, -18. , -16.8,  -2. ],
        [-10. ,   6. , -20. , -18. ,  -2. ],
        [ -9.6,   9.6, -25.5, -15.4,  -2. ],
        [  9.8,  -4.8,  18. ,  18.2,   2. ]])
