Question

matlab GUI中，两个控件间数据的调用

function pushbutton1_Callback(hObject, eventdata, handles)
x=1:4*pi
y=sin(x)
function pushbutton2_Callback(hObject, eventdata, handles)
这里调用上一个（function pushbutton1_Callback(hObject, eventdata, handles)）中的y
请问怎么弄

Answer 1

最简单的是将y定义为全局变量global y 在下一个里面直接调用

追问

function pushbutton1_Callback(hObject, eventdata, handles)
x=1:4*pi
y=sin(x)
global y

function pushbutton2_Callback(hObject, eventdata, handles)
z=y

是这样吗

追答

function pushbutton1_Callback(hObject, eventdata, handles)
global y
x=1:4*pi
y=sin(x)

function pushbutton2_Callback(hObject, eventdata, handles)
global y %这一个也要声明 y可以直接用了
