Code #1 :
# Python program explaining # numpy.ndarray.dot() function # importing numpy as geek import numpy as geek arr1 = geek.eye(3) arr = geek.ones((3, 3)) * 3 gfg = arr1.dot( arr ) print( gfg) |
Output :
[[ 3. 3. 3.] [ 3. 3. 3.] [ 3. 3. 3.]]
Code #2 :
# Python program explaining # numpy.ndarray.dot() function # importing numpy as geek import numpy as geek arr1 = geek.eye(3) arr = geek.ones((3, 3)) * 3 gfg = arr1.dot(arr).dot(arr) print( gfg) |
Output :
[[ 27. 27. 27.] [ 27. 27. 27.] [ 27. 27. 27.]]
