clf;
gcf=figure('Unit','normalized','Position',[0.15,0.3,0.75,0.4583],'Menubar','none','Name',…
'产生图形','NumberTitle','off','Color','r');
pbstart=uicontrol(gcf,'Style','push','Unit','normalized','Position',…[0.64,0.1,0.15,0.1],'string','绘图','call','t=0:pi/20:2*pi;…
plot(t,sin(t));axis([0 2*pi -1 1])');
yingli=uicontrol(gcf,'Style','Edit','Unit','normalized','Position',…[0.8,0.9,0.18,0.08],'back','w','HorizontalAlignment','left','string','ttt');
hpop=uicontrol…(gcf,'Style','push','string','按钮',Position',…[100,100,100,80],'call','set(yingli,"string","b")');
运行后按 按钮 控件 报错如下
??? Error: Missing variable or function.
??? Error while evaluating uicontrol Callback.
发现call 不能和 set 还有get 一起用，但是我的参考书上Call属性后面跟着的语句里面有Set,如'call','set(yingli,"string","b")哪位高手指导一下
