function h=m_line(long,lat,varargin);% M_LINE Create a line on a map%    M_LINE(LONG,LAT) adds the line in vectors LONG and LAT to the %    current axes. If LONG and LAT are matrices the same size, one %    line per column is added.% %    LINE returns a column vector of handles to LINE objects, %    one handle per line. LINEs are children of AXES objects.% %    The LONG,LAT pair can be followed by %    parameter/value pairs to specify additional properties of the lines.%    These are standard 'line' properties.%%    See also LINE, M_LL2XY% Rich Pawlowicz (rich@ocgy.ubc.ca) 17/Jan/1998% 8/Dec/98 - changed switch test to only 3 letters (thus letting%            "tag" properties through).% 18/july/00 - Fixed m_line so you could do clipping through it.% 6/Nov/00 - eliminate returned stuff if ';' neglected (thx to D Byrne)%% This software is provided "as is" without warranty of any kind.
