[Solved] Which of the following is the correct way to import and use Cholesky decomposition from scipy? — Ans: from scipy.linalg import cholesky L = cholesky(A, lower=True) | SciPy

SciPy - Linear Algebra (scipy.linalg)

Which of the following is the correct way to import and use Cholesky decomposition from scipy?

Afrom scipy.linalg import cholesky L = cholesky(A, lower=True)

Bimport scipy.cholesky as chol L = chol.decompose(A)

Cfrom scipy.linalg import cholesky L = cholesky(A, upper=True)

Dimport cholesky from scipy L = cholesky(A)

Step-by-Step Solution

Solution:

Step 1: Recall correct import syntax
The correct import is from scipy.linalg import cholesky.
Step 2: Check usage parameters
To get the lower-triangular matrix, use cholesky(A, lower=True). from scipy.linalg import cholesky L = cholesky(A, lower=True) matches this exactly.
Final Answer:
from scipy.linalg import cholesky\nL = cholesky(A, lower=True) -> Option A
Quick Check:
Correct import and lower=True parameter [OK]

Quick Trick: Use from scipy.linalg import cholesky and lower=True [OK]
