Image
I nverse of the matrix in Python. suppose we have a (2, 2) matrix.   >>>   A = np.array([[2, 1], [3, 3]])         >>> A.I                                   matrix([[ 1.        , -0.33333333],                   [-1.        ,  0.66666667]]) L ets dive in   steps behind inverse. First of all               1                 [2,  1]                                      (A[1,1]*A[2,2] - A[1,2]*A[2,1])[3,  3]   , put the values e.g :-   A[1, 1] = 2       1       =   1  [3   -1]     ...
