Now, Every row of the is given by a linear mixture of the r rows of R. Hence, the rows of R type a spanning set of the row Place of the and, through the Steinitz Trade lemma, the row rank of A cannot exceed r. This proves which the row rank of the is less than or equivalent to the column rank of the. This result may be placed on any matrix, so use The end result to the transpose of A. Since the row rank with the transpose of the would be the column rank of the along with the column rank in the transpose of the is the row rank of A, this establishes the reverse inequality and we get the equality in the row rank and also the column rank of the. (Also see Rank factorization.) Evidence using orthogonality[edit]
