interporthinc
Incremental orthogonal polynomial interpolation.
Syntax
[f, esys, eeval, edom] = interporthinc(x, fx, tol, inc)
Description
f = interporthinc(x, fx, tol, inc) interpolates an expression by using
Chebyshev or Legendre points. In this version an incremental scheme is
applied, and the interpolation degree is automatically found.
Inputs (required)
x = independent tau variavle (itau object).
fx = function (char).
Inputs (optional)
tol = tolerance for precicion (double).
inc = step of polynomial degree (integer).
Output
f = coeficients of interpolation (double vector).
esys = error in the linear system (double vector).
eeval = (max.) error in the evaluation (double scalar).
edom = error in the full domain (double vector).
