Inverse of a matrix using numpy

Question

I\'d like to use numpy to calculate the inverse. But I\'m getting an error:

\'numpy.ndarry\' object has no attribute I

To calculate inver

Answer 1

Another way to do this is to use the numpy matrix class (rather than a numpy array) and the I attribute. For example:

>>> m = np.matrix([[2,3],[4,5]])
>>> m.I
matrix([[-2.5,  1.5],
       [ 2. , -1. ]])
