View Profile, Fred G. Gustavson. View Profile, WebThe Schur complement arises when performing a block Gaussian elimination on the matrix M. In order to eliminate the elements below the block diagonal, one multiplies the matrix M by a block lower triangular matrix on the right as follows: where Ip denotes a p × p identity matrix. As a result, the Schur complement appears in the upper-left p × ...
