matlab 纯数据表格,MATLAB uitable表格数据更新处理

get获取到的data数据为cell格式，ginput获取的double类型数据需要转换成cell格式。直接将ginput获取的double类型数据set为uitable的data导致再向表格中添加数据时，提示串联的矩阵的维度不一致。

function pushbutton2_Callback(hObject, eventdata, handles)

a=cell(1,2);

b=ginput(1);

a(1,1)=num2cell(b(1,1));

a(1,2)=num2cell(b(1,2));

tarval=[num2cell(1.2),a];

table2data=get(handles.uitable2,‘data’);

if isempty(table2data{1,1})

pushbutton1_Callback(hObject, eventdata, handles)

set(handles.uitable2,‘data’,tarval);

h=plot(handles.axes1,b(1,1),b(1,2),‘o’);

set(h,‘handlevisibility’,‘off’);

text(handles.axes1,b(1,1),b(1,2),[’ 目标点’ num2str(1)]);

else

pushbutton1_Callback(hObject, eventdata, handles)

table2data=get(handles.uitable2,‘data’);

tarval=[table2data;tarval]

set(handles.uitable2,‘data’,tarval);

table2data=get(handles.uitable2,‘data’);

n = size(table2data,1);%目标点个数

for i=1:n

h=plot(handles.axes1,table2data{i,2},table2data{i,3},‘o’);

set(h,‘handlevisibility’,‘off’);

text(handles.axes1,table2data{i,2},table2data{i,3},[’ 目标点’ num2str(i)]);

end
