Hi! I have a question about Linear Algebra. Let X and Y be two matrices with 4 rows and 5 columns. The rank of X and Y is 3. May I ask how to get the lower bound and upper bound of the rank of X_T*Y? Besides, how to proved it? I am so confused about it. Could please tell me how to solve it? Thank you so much!
