WebThe Julia function condcomputes condition numbers of rectangular matrices in the 2-norm. When the normal equations are solved, perturbations to the data can be amplified by a factor \(\kappa(\mathbf{A}^T\mathbf{A})\). As an algorithm, the normal equations begin by computing the \(n\times n\)system
