%
% Fourier interpolation. If @var{x} is a vector, then @var{x} is
% resampled with @var{n} points. The data in @var{x} is assumed to be
% equispaced. If @var{x} is an array, then operate along each column of
% the array separately. If @var{dim} is specified, then interpolate
% along the dimension @var{dim}.
%
% @code{interpft} assumes that the interpolated function is periodic,
% and so assumptions are made about the end points of the interpolation.
