NumPy: Compute the determinant of a given square array
NumPy: Linear Algebra Exercise-4 with Solution
Write a NumPy program to compute the determinant of a given square 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.
In the case of a 2 × 2 matrix the determinant may be defined as:
Sample Solution :
Python Code :
import numpy as np from numpy import linalg as LA a = np.array([[1, 0], [1, 2]]) print("Original 2-d array") print(a) print("Determinant of the said 2-D array:") print(np.linalg.det(a))
Original 2-d array [[1 0] [1 2]] Determinant of the said 2-D array: 2.0
