function varargout=plot4(x,y,z,c,varargin);

% PLOT4  Plot colored lines and points in 3-D space
%  
%    PLOT3(x,y,z,c), where x, y, z and c are four vectors of the same length N,
%    plots a line in 3-space through the points whose coordinates are the
%    elements of x, y and z, colored occording to the values in c. The line
%    consists of N-1 line segments.
%  
%    Various line types, plot symbols and colors may be obtained with
%    PLOT3(X,Y,Z,s) where s is a 1, 2 or 3 character string made from
%    the characters listed under the PLOT command.
%  
%    Example: A helix:
%  
%        t = 0:pi/50:4*pi;
%        plot4(sin(t),cos(t),t.^2,t,'.-');
%  
%    PLOT4 returns a column vector of handles to lineseries objects, one
%    handle per line segment.
%
%    See also plot, plot3, line, axis, view, mesh, surf.
