How to Create a Vector or Matrix in Python?

This recipe helps you Create a Vector or Matrix in Python


Recipe Objective

Have you ever tried to create a transpose of a vector or matrix? Is"nt it very easy to calculate manually but if you have to calcuate transpose of many matrises then it may not be possible to do it manually.

So this is the recipe on how we can Create & Transpose a Vector or Matrix.

Step 1 - Import the library

import numpy as np

We have only imported numpy which is needed.

Step 2 - Setting up the Vector and Matrix

We have created a vector and matrix using array and we will find transpose of it. vector = np.array([10, 20, 30, 40, 50, 60]) print("Original Vector: ", vector) matrix = np.array([[11, 22, 33], [44, 55, 66], [77, 88, 99]]) print("Original Matrix: ", matrix)

Step 3 - Calculating transpose of vector and matrix

We can make transpose of vector and matrix by using T function, i.e. applying .T after the vector and matrix. V = vector.T print("Transpose Vector: ", V) M = matrix.T print("Transpose Matrix: ", M) So the output comes as

Original Vector: 
 [10 20 30 40 50 60]

Original Matrix: 
 [[11 22 33]
 [44 55 66]
 [77 88 99]]
Transpose Vector: 
 [10 20 30 40 50 60]
Transpose Matrix: 
 [[11 44 77]
 [22 55 88]
 [33 66 99]]
