SciPy - Linear Algebra (scipy.linalg)

What is the output of the following code?

import numpy as np
from scipy.linalg import eig
A = np.array([[2, 0], [0, 3]])
values, vectors = eig(A)
print(values)

A[2.+0.j 3.+0.j]

B[0.+2.j 0.+3.j]

C[5.+0.j 0.+0.j]

D[2 3]

Step-by-Step Solution

Solution:

Step 1: Understand matrix and eig function
Matrix A is diagonal with values 2 and 3 on the diagonal. Eigenvalues of a diagonal matrix are the diagonal elements.
Step 2: Predict output of eig
scipy.linalg.eig returns eigenvalues as complex numbers, so output will be [2.+0.j 3.+0.j].
Final Answer:
[2.+0.j 3.+0.j] -> Option A
Quick Check:
Diagonal matrix eigenvalues = diagonal elements [OK]

Quick Trick: Diagonal matrix eigenvalues = diagonal entries as complex numbers [OK]
