  # Python | Numpy matrix.getI ()

NumPy | Python Methods and Functions

Using the ` Numpy matrix.getI () ` method, we can get a multiplicative inverse of the same size as for this matrix.

Syntax: `matrix.getI()`

Return: Return multiplicative inverse of a given matrix

Example # 1:
In this example, we see that we can get the multiplicative inverse using the ` matrix.getI () `.

 ` # import important module into python ` ` import ` ` numpy as np `   ` # make a matrix with NumPy ` ` gfg ` ` = ` ` np.matrix (` `` [6, 1; 2, 3] `` `) ` ` `  ` # using the matrix.getI () method ` ` geeks ` ` = ` ` gfg.getI () `   ` print ` ` (geeks) `

Output:

` [[0.1875 -0.0625] [-0.125 0.375]] `

Example # 2:

 ` # import important module in python ` ` import ` ` numpy as np `   ` # make a matrix with NumPy ` ` gfg ` ` = ` ` np.matrix (< / code> `[1, 2, 3; 4, 5, 6; 7, 8, 9] ` ) ``    # using the matrix.getI () method geeks = gfg.getI ()   print (geeks) `

Exit:

` [[-4.50359963e + 15 9.00719925e + 15 -4.50359963e + 15] [9.00719925e + 15 -1.80143985e + 16 9.00719925e + 15] [- 4.50359963e + 15 9.00719925e + 15 -4.50359963e + 15]] `
