NumPy: Compute the condition number of a given matrix

NumPy: Linear Algebra Exercise-14 with Solution

Write a NumPy program to compute the condition number of a given matrix.

From Wikipedia: In the field of numerical analysis, the condition number of a function with respect to an argument measures how much the output value of the function can change for a small change in the input argument. This is used to measure how sensitive a function is to changes or errors in the input, and how much error in the output results from an error in the input.

Sample Solution:

Python Code :

import numpy as np
m = np.array([[1,2],[3,4]])
print("Original matrix:")
result =  np.linalg.cond(m)
print("Condition number of the said matrix:")

Sample Output:

Original matrix:
[[1 2]
 [3 4]]
Condition number of the said matrix:

Python: Use Enumerate() In for Loops

>>> students = ('John', 'Mary',  'Mike')
>>> for i, student in enumerate(students):
  ...     print(f'Iteration:  {i}, Student: {student}')
Iteration: 0, Student: John
Iteration: 1, Student: Mary
Iteration: 2, Student: Mike
>>> for i, student in enumerate(students,  35001):
  ...      print(f'Student Name: {student}, Student ID #: {i}')
Student Name: John, Student ID #: 35001
Student Name: Mary, Student ID #: 35002
Student Name: Mike, Student ID #: 35003
