of A; This can be the dimension from the column Room of the (the column space currently being the subspace of Fm created with the columns of A, which is in actual fact just the graphic of your linear map f involved to some). Row rank – dimension of row Room[edit]

It is straightforward to indicate that neither the row rank nor the column rank are changed by an elementary row Procedure.
