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]]
