In this paper, we first give the representation of the general solution of the following least-squares problem (LSP): given a matrix X โˆˆ R nร—p and symmetric matrices ) is the r ร— r leading principal submatrix of the matrix A. We then consider a best approximation problem: given an nร—n symmetric mat
