Matrizes elementares - Parte 1

Hello everyone! In this video, we explore some properties of elementary matrices, which are matrices obtained from the identity matrix by applying an elementary operation. We've already made a video about elementary operations, which you can watch at    • [Sistemas Lineares] Operações Elementares   More specifically, we focus on the elementary operation that replaces a row with its sum and a multiple of another row, and we explore some properties of the corresponding elementary matrices. We'll use this in a future video to explore LU factorization of matrices. Hope you enjoy!
