设计GUI界面，解方程解这个方程a*x+b*y-1=0,c*x+d*y-2=0。abcd为输入量。然后输出x y。% 获取文本框内容a = str2num(get(handles.edit_num1,&#39;String&#39;)); b = str2num(get(handles.edit_num2,&#39;String&#39;)); c = str2num(get(handles.edit_num3,&#39;String&#39;)); d = str2num(get(handles.edit_num4,&#39;String&#39;)); syms x ym=solve(a*x+b*y-1,c*x+d*y-2);set(handles. edit_x,&#39;String&#39;,m(1)); set(handles. edit_y,&#39;String&#39;,m(2)); guidata(hObject, handles); %更新结构体但是没有输出值。这是为什么呀？
