medium📝 Predict Output Q4 of 15

MATLAB - Linear Algebra

A = [1 2 3; 4 5 6];
B = A';
disp(B);

A[1 4; 2 5; 3 6]

B[1 2 3; 4 5 6]

C[1 4 2; 5 3 6]

D[1 4 5; 2 3 6]

Step-by-Step Solution

Solution:

Step 1: Understand original matrix A
A is a 2x3 matrix: first row [1 2 3], second row [4 5 6].
Step 2: Transpose matrix A
Transpose swaps rows and columns, so B becomes 3x2 with columns of A as rows: [1 4; 2 5; 3 6].
Final Answer:
B = [1 4; 2 5; 3 6] -> Option A
Quick Check:
Transpose swaps rows and columns = [1 4; 2 5; 3 6] [OK]

Quick Trick: Transpose flips rows and columns values [OK]
