buttondownfcn指用鼠标单击该pushbutton，keypressfcn指在键盘上按下一个键。buttondownfcn就是pushbutton的其中一个callback函数，选择某个属性后系统会自动创建该属性的一个callback函数模板，然后自己再添加需要的代码。
function pushbutton1_Callback(hObject, eventdata, handles) a=get(handles.edit1,'string'); mat1=str2num(a); b=roots(mat1); set(handles.edit3,'string',num2str(b)); function pushbutton2_Callback(hObject, eventdata, handles) h=30*rand(1,2); set(handles.pushbutton2,'position',[h(1)...
simulink里面加载模糊控制器，如果保存文件形式的记得用单引号扩起来，要不然就要将对应的模块加载到工作区并且名字要一致才行

病句1：t=0:0.001:1; t的维数（1001）与signal的维数（5000）不相等 应改为：t=linspace(0,1,5000)病句2：y32=sin(2*pi*32*t) 两个行向量相乘，应使用点乘运算 应改为：y32=sin(2*pi*32.*t)其余，都ok

在用eq（即==）的时候，两个所比较的应该是同维度的数组，或数组与一个标量（即数字）。比较的结果也是一个数组。你'value'=='Max'这句就有误，因为value和Max的长度不一样！
When I am selecting a pushbutton in a MATLAB GUI, I can trigger its callback by a left click or pressing the space bar. Instead of <SPACE> key press I would rather trigger the button callback by pressing <ENTER> key. Accepted Answer ...
