Mandatory Input Parameters

Optional Input Parameters

None

Return Value

Examples

>>> import numpy as np
>>> # The determinant of a 2-D array [[a, b], [c, d]] is ad - bc.
>>> a = np.array([[1,2],[3,4]])
>>> a
array([[1, 2],
       [3, 4]])
>>> 
>>> np.linalg.det(a)
-2.0 
>>> 
>>> a = np.array([[[1,2],[3,4]], [[1,2],[2,1]], [[1,3],[3,1]]])
>>> a
array([[[1, 2],
        [3, 4]],

       [[1, 2],
        [2, 1]],

       [[1, 3],
        [3, 1]]])
>>> 
>>> np.linalg.det(a)
array([-2., -3., -8.])
