How to find the Rank of a Matrix?

This recipe helps you find the Rank of a Matrix


Recipe Objective

Finding the Rank of a matrix manually isn"t a time taking process. So have you tried to do it in python.

So this is the recipe on how we can find the Rank of a Matrix.

Step 1 - Loading Library

We have imported numpy which is needed. import numpy as np

Step 2 - Creating a Matrix

We have created a matrix by using np.array with different values in it. matrixA = np.array([[1, 2, 3, 23], [4, 5, 6, 25], [7, 8, 9, 28], [10, 11, 12, 41]])

Step 3 - Calculating Rank

We have calculated rank of the matrix by using numpy function np.linalg.matrix_rank and passing the matrix through it. print("The Rank of a Matrix: ", np.linalg.matrix_rank(matrixA)) So the output comes as

The Rank of a Matrix:  3
