MATLAB - Cell Arrays and Structures
Given
C = {5, 10; 15, 20};, what does C(2,1) return?Given C = {5, 10; 15, 20};, what does C(2,1) return?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify indexing type
Parentheses()indexing returns a cell array subset, not the content.Step 2: Apply indexing to given cell array
C(2,1)returns a 1x1 cell array containing the element at row 2, column 1, which is 15.Final Answer:
A cell array containing the number 15 -> Option AQuick Check:
Parentheses indexing returns cell array = D [OK]
Quick Trick: Parentheses keep cell structure, curly braces extract content [OK]
Common Mistakes:
- Expecting a numeric value instead of a cell
- Mixing up row and column indices
