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