%%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
