Another suggestion, and this one also makes the parallel to Matlab. Make sure it works for vectors:

>>> a=np.array([7,11,250])
>>> nextpow2(a)
array([ 3., 4., 8.])

In [27]: tab.searchsorted([7,11,250])
Out[27]: array([3, 4, 8])

In [28]: np.frexp([7,11,250])[1]
Out[28]: array([3, 4, 8], dtype=int32)
