Rank A^T = Rank A

Описание: In this video, I give a neat consequence of the Fundamental Rank Theorem (link below) by showing that A and A^T always have the same rank. Suprising, because they usually don't look the same!

Fundamental Rank Theorem:    • Fundamental Rank Theorem  

Another proof of this fact using dual spaces:    • Rank A^T = Rank A
