[MATLAB GUI] 求助：如何编写可接受输入的编辑框

[kuca]

想写一个在编辑框中输入频率 就会产生相应波形的图像
有部分程序 不过不知道可接受输入的编辑框如何写 各位帮忙

>> clf reset
H=axes('unit','normalized','position',[0,0,1,1],'visible','off');
set(gcf,'currentaxes',H);
str='\fontname{隶书}波形曲线';
text(0.12,0.93,str,'fontsize',25);
h_fig=get(H,'parent');
set(h_fig,'unit','normalized','position',[0.1,0.2,0.7,0.4]);
h_axes=axes('parent',h_fig,...
'unit','normalized','position',[0.1,0.15,0.55,0.7],...
'xlim',[0 2],'ylim',[-1.5 1.5],'fontsize',8);
h_text=uicontrol(h_fig,'style','text',...
'unit','normalized','position',[0.67,0.73,0.25,0.14],...
'horizontal','left','string',{'输入频率','h ='});
