Notes

What is the Transpose?

The transpose of matrix A is written A^T. It is formed by swapping the row and column index of every element. A 2×3 matrix becomes a 3×2 matrix.

Example: 2×3 → 3×2

Original A (2×3):

123
456

A^T (3×2):

14
25
36
A symmetric matrix satisfies A = A^T. Key identity: (AB)^T = B^T A^T — note the reversed order.

Frequently Asked Questions

What is the transpose of the transpose?

(A^T)^T = A — transposing twice returns the original matrix.

What is a symmetric matrix?

A matrix A is symmetric if A = A^T, meaning A[i][j] = A[j][i] for all i, j. Symmetric matrices must be square.

How does the transpose interact with matrix multiplication?

(AB)^T = B^T A^T — the transpose reverses the order of multiplication. This is a frequently used identity.
