matlab上矩陣中一個(gè)數(shù)據(jù)減去下一個(gè)數(shù)據(jù)?
非常簡(jiǎn)單。只需設(shè)置表的數(shù)據(jù)屬性。例如:
函數(shù)pushbutton1uCallback(hObject,eventdata,handles)%hObject handle to pushbutton1(請(qǐng)參閱GCBO)%eventdata reserved-將在未來(lái)版本的MATLAB中定義%handles結(jié)構(gòu),帶有句柄和用戶數(shù)據(jù)(請(qǐng)參閱GUIDATA)a=magic(5)set(句柄.uitable1,data,a)
MATLAB的CALLBACK函數(shù)?
,使用全局變量,openingfcn函數(shù)輸出1uopeningfcn(hObject,eventdata,handles,varargin)globalhObject1handles1handles.output=hObjecthObject1=hObjecthandles1=handlesguidata輸出然后每個(gè)程序都可以用全局object1handles1guidata(object1,handles1)uWindowButtonMotionFCN(hobject,eventdata,handles)P=get(GCA,“currentpoint”)%get handle msgstr=sprintf(“x=%3.3F,y=%3.3F”,P(1),P(2))%get position Xinshi=TXT(“style”,“text”,“position”,[100 20],“string”,msgstr)
