+% PROGRAM NAME: Plot horizontal lines
+% FILE: plotvertline.m
+% AUTHOR: Andri M. Gretarsson
+% DATE: 02/03/03
+%
+% SYNTAX: linehandles=plothorline(y,xmin,xmax <,marker,plotstyle>)
+%
+% Plots horizontal lines at the positions listed in the vector y. The vertical
+% lines extend from xmin to xmax and are ploted with the markerstyle and
+% color defined by marker if specified (same syntax as the marker in matlab's
+% built in function plot. Exits with hold set to off. If plotstyle is specified
+% then the plotstyle will be linear-linear, lin-log, log-lin or log-log,
+% depending on whether plotstyle is 'plot', 'semilogx', 'semilogy', or 'loglog'.
+%
+% If 'marker' is a string whose first character is an apostrophe ('),
+% the marker string in interpreted literally as part of the command, as in:
+% eval(['plot([xmin xmax],[y(i) y(i)],',marker,')']);
+%
+% If the first character of marker is not an apostrophe, the marker string is
+% just inserted into the command as usual without using eval, namely:
+% plot([xmin xmax],[y(i) y(i)],marker).
+%
+% Thus, for example:
+% marker = '''b-'',''LineWidth'',2' results in the plot command
+% plot(x,y,'b-','LineWidth',2) being evaluated.
+%
+% marker = 'b-' has the same effect as marker = '''b-''', namely
+% plot(x,y,'b-'), in the first case directly via plot(x,y,'b-') and
+% in the second case via eval(['plot(x,y,',marker,')']).
+%
+% If xmin=0 and xmax=0, then ymin and ymax are obtained from the current
+% axes.
