Now, each row of A is provided by a linear mixture of the r rows of R. As a result, the rows of R variety a spanning list of the row space of A and, because of the Steinitz exchange lemma, the row rank of the can't exceed r. This proves which the row rank of the is fewer than or equal on the column rank of the. This outcome could be placed on any matrix, so utilize The end result towards the transpose of A. For the reason that row rank with the transpose of the may be the column rank of the and the column rank from the transpose of A may be the row rank of the, this establishes the reverse inequality and we attain the equality from the row rank as well as column rank of the.
