NumPy: Compute the determinant of an array

NumPy: Linear Algebra Exercise-11 with Solution

Write a NumPy program to compute the determinant of an array.

From Wikipedia: In linear algebra, the determinant is a value that can be computed from the elements of a square matrix. The determinant of a matrix A is denoted det(A), det A, or |A|. Geometrically, it can be viewed as the scaling factor of the linear transformation described by the matrix.

NumPy Linear algebra: Compute the determinant of an array

Sample Solution :

Python Code :

import numpy as np
a = np.array([[1,2],[3,4]])
print("Original array:")
print(a)
result =  np.linalg.det(a)
print("Determinant of the said array:")
print(result)

Sample Output:

Original array:
[[1 2]
 [3 4]]
Determinant of the said array:
-2.0
