function [xc, yc]=carpetconvert(x1, x2, y, offset, x1p, x2p)
%CARPETCONVERT Converts points into carpet plot coordinates.
% [xc, yc]=carpetconvert(x1, x2, y, offset, x1p, x2p) converts the points
% x1p, x2p into carpet plot coordinates defined by (x1, x2, y, offset)
% as described in CARPET.
%
% The converted points are returned in [xc, yc].
