Which of the following is the correct way to create a CSC matrix from a dense NumPy array
arr in Python using SciPy?Which of the following is the correct way to create a CSC matrix from a dense NumPy array arr in Python using SciPy?
easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Identify correct SciPy function for CSC
The function to create a CSC matrix isscipy.sparse.csc_matrix().Step 2: Check options for syntax correctness
scipy.sparse.csc_matrix(arr)uses the correct function and syntax.scipy.sparse.csr_matrix(arr)creates CSR, not CSC. Options C and D are invalid functions.Final Answer:
scipy.sparse.csc_matrix(arr) -> Option AQuick Check:
Use csc_matrix() to create CSC format [OK]
Quick Trick: Use csc_matrix() to create CSC sparse matrix [OK]
Common Mistakes:
MISTAKES- Using csr_matrix instead of csc_matrix
- Trying non-existent functions like dense_matrix
- Missing _matrix suffix in function name
