We desire to find a correlation matrix R of a given rank that is as close as possible to an input matrix R, subject to the constraint that specified elements in R must be zero. Our optimality criterion is the weighted Frobenius norm of the approximation error, and we use a constrained majorization a
The main aim of this article is to give a combinatorial method for computing the Fischer matrices of the generalised symmetric group. It is shown that generalised Young tableaux and tabloids play a crucial role in the calculation of the Fischer matrices. In particular, a recursive method which is si
