Question

在MATLAB GUI设计中，如何通过EDIT读入如[1 2 3]这样的数组？？？急……

Answer 1

aa = get(h,'String'); %读入edit句柄h的内容
bb = str2num(aa); %将字符串转换成数组

追问

试了一下 ，似乎还是不行……其实我想实现数组的加法，如从一个EDIT输入[1 2 3]，实现a=[1 2 3]+1=[2 3 4],然后从另外一个EDIT里输出[2 3 4]，还请指教……

追答

str = ['a = str2num(get(h1,''String''));','b = a+1;','set(h2,''String'',num2str(b));'];
h = figure('Units','Normalized');
h1 = uicontrol('Units','Normalized','Parent',h,'Position',[0.1 0.5 0.2 0.1],'Style','Edit');
h2 = uicontrol('Units','Normalized','Parent',h,'Position',[0.4 0.5 0.2 0.1],'Style','Edit');
h3 = uicontrol('Units','Normalized','Parent',h,'Position',[0.1 0.3 0.2 0.1],'Callback',str,'String','Confirm');

Answer 2

aa = get(h,'String'); %读入edit句柄h的内容
bb = str2num(aa); %将字符串转换成数组
