If a is a symmetric matrix, is A* also a symmetric matrix? How to prove it? What is the transposed symbol of a matrix? Do both t and a' represent the transposition of a?
The matrix A(nm) is symmetric, and A(nm)=A(mn).
* * * The yoke array A*(nm)=(A(nm))*=(A(mn))*=A*(mn) is A* symmetric.
Transposition is generally marked with a t in the upper right corner.
It's just a habit instead. Just explain it in solving the problem, don't delve into it.
