本文介绍了一种在MATLAB中初始化用户界面控件的方法，通过设置多个输入控件的默认值为'N/A'或'-'，确保了在未输入有效数据前，控件显示统一的占位符。
set(handles.in1,'String','N/A');set(handles.in2,'String','N/A');
set(handles.in3,'String','N/A');set(handles.in4,'String','N/A');
set(handles.in5,'String','N/A');set(handles.in6,'String','N/A');
set(handles.input1,'String','-');set(handles.input2,'String','-');
set(handles.input3,'String','-');set(handles.input4,'String','-');
set(handles.input5,'String','-');set(handles.input6,'String','-');
