matlab界面edit text输入一维数组

我要在matlab界面edit text中输入以为数组，不是一个数，用a=str2num(get(handles.edit1,'string')); 显示有错误definition1是函数名
Error in ==> definition1>pushbutton1_Callback at 405
a=str2num(get(handles.edit25,'string'))

Error in ==> gui_mainfcn at 75
feval(varargin{:});

Error in ==> definition1 at 44
gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback.
