紧急求助!关于matlab中GUI用户图形界面通过edit输入调用函数问题!

如何在gui界面的edit中调用一个函数,而且是输入函数名,直接调用给函数,可以实现吗?不行的话,有别的办法不?如果有的话能发一段源代码不?

是可以的,可以见张志涌《精通matlab6.5版》的一个例子:(图片中的绘图指令输入框就是你说的命令输入框,可以参考这个例子,实现你的功能,主要是eval的使用,用法你可以查看eval的帮助)

【例10.4.3.3-1】目标:制作一个能绘制任意图形的交互界面。它包括:可编辑文本框、弹出框、列表框。本例的关键内容是:如何使编辑框允许输入多行指令。

set(hpush,'callback','calledit(hedit,hpop,hlist)'); % <28>

[calledit.m]%这个是子函数

function calledit(hedit,hpop,hlist)

ct=get(hedit,'string'); % <2>

vpop=get(hpop,'value'); % <3>

vlist=get(hlist,'value'); % <4>

if ~isempty(ct) % <5>

eval(ct') % <6>

popstr={'spring','summer','autumn','winter'}; % <7>

liststr={'grid on','box on','hidden off','axis off'};% <8>

invstr={'grid off','box off','hidden on','axis on'};% <9>

colormap(eval(popstr{vpop})) % <10>

vv=zeros(1,4);vv(vlist)=1;

for k=1:4

if vv(k);eval(liststr{k});else eval(invstr{k});end

end

end
