B = A';
disp(size(B));
What will be the output of this MATLAB code?
medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Identify size of A
A has 3 rows and 2 columns, so size(A) = [3 2].Step 2: Transpose A to get B
Transpose swaps rows and columns, so size(B) = [2 3].Final Answer:
Size of B is [2 3] -> Option CQuick Check:
Transpose swaps size dimensions = [2 3] [OK]
Quick Trick: Transpose swaps matrix dimensions [OK]
Common Mistakes:
- Confusing original size with transposed size
- Mixing rows and columns
- Assuming size unchanged
