Interpolation and Polynomial Approximation

working with grids having large numbers of intervals one typically assigns a set of low degree (n = 1, 2, or 3) basis functions to each adjacent set of n+1 = 2, 3, or 4 nodes. ... Piecewise polynomial interpolation with quadratic. P(x) = (0) + (16) + (48); 0 ( x ( 2. ................
