Python Coding challenge - Day 347| What is the output of the following Python Code?

 

Code Explanation:

from scipy.linalg import det  

matrix = [[2, 3], [1, 4]]  

result = det(matrix)  

print(result)

from scipy.linalg import det:

This line imports the det function from the scipy.linalg module. The det function is specifically used for calculating the determinant of a matrix.

matrix = [[2, 3], [1, 4]]:

Here, you define a 2x2 matrix with the values:

[[2, 3],  

 [1, 4]]

This is a square matrix (2 rows and 2 columns).

result = det(matrix):

The det() function is used to compute the determinant of the matrix. For a 2x2 matrix, the determinant can be calculated using the formula:

det(A)=(a×d)−(b×c)

So for the matrix [[2, 3], [1, 4]], we get:

det(A)=(2×4)−(3×1)=8−3=5

This means the determinant of this matrix is 5.

print(result):

This line prints the computed result of det(matrix), which is 5.

Answer:

B: The determinant of the matrix
