%RESAMPLING CHEBFUN resample option
% RESAMPLING ON forces the Chebfun constructor to sample a function at
% all Chebyshev points as it adapts the number of nodes needed for an
% accurate representation. This option is recommended when working with
% chebops or if the values of the function depend on the number of
% RESAMPLING OFF allows the constructor to sample only at new nodes
% whenever the number of nodes is doubled. This option is recommended
% when the evaluations are time consuming.
% RESAMPLING is OFF by default, by itself, displays the current splitting
