%%自制一个下拉菜单表的用户菜单，背景颜色设为蓝色
figure
h_menu=uimenu(gcf,\'label\',\'color\');%%用户顶层菜单项color
h_submenul=uimenu(h_menu,\'label\',\'blue\',\'callback\',\'set(gcf,\'\'color\'\',\'\'blue\'\')\');%制作下拉菜单项blue
h_submenu2=uimenu(h_menu,\'label\',\'red\',\'callback\',\'set(gcf,\'\'color\'\',\'\'red\'\')\');%制作下拉菜单项red

特别提醒一下：其中“color”要用两个英文字符的单引号，不是一个双引号。不然响应不了哦

%%给菜单贴上检录符
%%每个功能区的两个菜单项是相互对立的，可见功能属性
