Real line losses in the power sector were recorded at 18.3 percent, however, the power sector regulator permitted the recovery of 16.3 billion, which added Rs202 billion to the already piling circular debt.
In the beginning of the 80's, Walter Gautschi developed the constructive theory of orthogonal polynomials on the real line, including effective algorithms for numerically generating orthogonal polynomials with respect to an arbitary measures, and provided rigorus and detailed stability analyses of these algorithms.

The standard pseudospectral matrix representations of linear differential operators are based on Lagrange collocation on the real line. These representations were proposed by Calogero in the context of numerical solving of eigenvalue and boundary value problems for linear ODEs [20, 21]; see also [8, 22-25].
