numpy.inner() in python
numpy.inner(arr1, arr2)
: Computes the inner product of two arrays.
Parameters : arr1, arr2 : array to be evaluated. Return: Inner product of the two arrays.
Code #1 :
# Python Program illustrating # numpy.inner() method import numpy as geek # Scalars product = geek.inner( 5 , 4 ) print ( "inner Product of scalar values : " , product) # 1D array vector_a = 2 + 3j vector_b = 4 + 5j product = geek.inner(vector_a, vector_b) print ( "inner Product : " , product) |
Output:
inner Product of scalar values : 20 inner Product : (-7+22j)
Code #2 : As normal matrix multiplication
# Python Program illustrating # numpy.inner() method import numpy as geek # 1D array vector_a = geek.array([[ 1 , 4 ], [ 5 , 6 ]]) vector_b = geek.array([[ 2 , 4 ], [ 5 , 2 ]]) product = geek.inner(vector_a, vector_b) print ( "inner Product : \n" , product) product = geek.inner(vector_b, vector_a) print ( "\ninner Product : \n" , product) |
Output:
inner Product : [[18 13] [34 37]] inner Product : [[18 34] [13 37]]
