datetick2

This simple script an extension of datetick for plotyy.

The datetick doesn't work well for plotyy due to two different axis properties. This script use for plotyy instead of datetick with one more input as
% haxes = plotyy(x1,y1,x2,y2)
% datetick2('x','mm/dd',haxes);
% or
% datetick2('x',4,haxes);
It basically same to datetick expect additional axes information input.
