With the help of Numpy matrix.getI()
method, we can get the multiplicative inverse of the same size as of our given matrix.
Syntax : matrix.getI()
Return : Return multiplicative inverse of given matrix
Example #1 :
In this example we can see that we are able to get the multiplicative inverse with the help of method matrix.getI()
.
import numpy as np
gfg = np.matrix( '[6, 1; 2, 3]' )
geeks = gfg.getI()
print (geeks)
|
Output:
[[ 0.1875 -0.0625]
[-0.125 0.375 ]]
Example #2 :
import numpy as np
gfg = np.matrix( '[1, 2, 3; 4, 5, 6; 7, 8, 9]' )
geeks = gfg.getI()
print (geeks)
|
Output:
[[ -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]]
