Preliminaries



In [1]:

    
# Load library
import numpy as np

Create Two Vectors



In [2]:

    
# Create two vectors
vector_a = np.array([1,2,3])
vector_b = np.array([4,5,6])

Calculate Dot Product (Method 1)



In [3]:

    
# Calculate dot product
np.dot(vector_a, vector_b)









    Out[3]:





32

Calculate Dot Product (Method 2)



In [4]:

    
# Calculate dot product
vector_a @ vector_b









    Out[4]:
