Evaluation of minors associated to weighing matrices
A weighing matrix \(W=W(n,n-k)\) is a \((0,1,-1)\)-matrix satisfying the equation \(W^TW=WW^T=(n-k) I_n,\) here \(n\) is even and \(k\geq 1\). It is said that this matrix has order \(n\) and weight \((n-k)\). The paper deals with the analytic formulas for minors of weighting matrices. In addition some algorithms to compute \((n-j)\times (n-j)\)-minors of \(W(n,n-k)\) are presented and analyzed by means of considerable experimental data.
