Find the error in this MATLAB code snippet:
A = [1 2; 3 4];
B = A';
C = B';
disp(C);
ATranspose operator used incorrectly
BNo error, code is correct
CMatrix dimensions mismatch
DVariable C is not assigned properly
Step-by-Step Solution
Solution:
  1. Step 1: Analyze transpose operations

    B = A' transposes A, then C = B' transposes B back to original.
  2. Step 2: Check for errors

    All syntax and assignments are correct, no dimension mismatch or errors.
  3. Final Answer:

    Code is correct with no errors -> Option B
  4. Quick Check:

    Double transpose returns original matrix [OK]
Quick Trick: Double transpose returns original matrix [OK]
Common Mistakes:
  • Thinking transpose changes matrix permanently
  • Confusing variable assignments
  • Assuming syntax error where none exists
