[Solved] Identify the error in the following code snippet for solving a sparse system: from scipy.sparse.linalg import spsolve A = [[1, 0], [0, 2]] b = [1, 4] x = spsolve(A, b) | SciPy

SciPy - Sparse Linear Algebra

Identify the error in the following code snippet for solving a sparse system:

from scipy.sparse.linalg import spsolve
A = [[1, 0], [0, 2]]
b = [1, 4]
x = spsolve(A, b)

AVector b should be a sparse matrix

Bspsolve requires three arguments

CMatrix A should be a sparse matrix, not a list of lists

DNo error, code runs correctly

Step-by-Step Solution

Solution:

Step 1: Check input types for spsolve
spsolve expects matrix A to be a sparse matrix type, not a plain Python list.
Step 2: Identify correct input format
Convert A to a sparse matrix like csr_matrix before calling spsolve.
Final Answer:
Matrix A should be a sparse matrix, not a list of lists -> Option C
Quick Check:
Input type error = Matrix A must be sparse matrix [OK]

Quick Trick: Convert A to sparse matrix before spsolve [OK]
