SUMMARY
Every m×n matrix A with m linearly independent rows can be derived from an n×n matrix by removing the last n − m rows. This conclusion is based on the properties of linear independence and matrix dimensions. The discussion highlights a common misunderstanding regarding the addition of rows instead of deletion, emphasizing the importance of maintaining the integrity of linear independence in matrix operations.
