Symmetric Rank-1 Update

This operation updates matrix A by

displaymath14385

Matrix A is of dimension tex2html_wrap_inline14391 and vector x is of length n . Matrices L and U indicate the lower and upper triangular part of matrix A , respectively. We indicate the lower and upper triangular part of matrix tex2html_wrap_inline14403 by tex2html_wrap_inline14405 and tex2html_wrap_inline14407 , respectively.
