Preliminaries



In [13]:

    
# Load library
import numpy as np

Create Vector



In [14]:

    
# Create vector
vector = np.array([1, 2, 3, 4, 5, 6])

Create Matrix



In [15]:

    
# Create matrix
matrix = np.array([[1, 2, 3],
                   [4, 5, 6],
                   [7, 8, 9]])

Transpose Vector



In [16]:

    
# Tranpose vector
vector.T









    Out[16]:





array([1, 2, 3, 4, 5, 6])

Transpose Matrix



In [17]:

    
# Transpose matrix
matrix.T









    Out[17]:





array([[1, 4, 7],
       [2, 5, 8],
       [3, 6, 9]])
