% Generate a regular mesh from irregular data using interpolation.
% The function is defined by @code{@var{z} = f (@var{x}, @var{y})}.
% The interpolation points are all @code{(@var{xi}, @var{yi})}. If
% @var{xi}, @var{yi} are vectors then they are made into a 2D mesh.
%
% The interpolation method can be @code{'nearest'}, @code{'cubic'} or
% @code{'linear'}. If method is omitted it defaults to @code{'linear'}.
