Homework Statement
Let A be a matrix
Then the following is true or false. (No need to explain why)
a) rank(A) = rank(At)
b) dim(Nul(A)) = dim(Nul(At)
The Attempt at a Solution
They are both true false right? The transpose swaps their row and columns which makes them interchanged
rank(A) = dim(Nul(At)
rank(At) = dim(Nul(A))
