wrong type variable in uitable
显示 更早的评论
function startupFcn(app, set)
app.InstrumTab=LoadInstrum_Struct(set);
app.Setting=set;
app.UITable.Data=app.InstrumTab;
app.UITable.ColumnName=["ProductName";"Ticker";"PointValue";"IntradayMargin";"OvernightMargin";"Slippage(x trade)";"MiniContractTicker";"PointValue1";"IntradayMargin1";"OvernightMargin1";"Slippage1(x trade)";"MicroContractTicker";"PointValue2";"IntradayMargin2";"OvernightMargin2";"Slippage2(x trade)";"Group";"Currency";"ExtraMinUnit"];
app.UITable.ColumnEditable=true;
app.UITable.VariableTypes={'char','char','double','double','double','double','char','double','double','double','double','char','double','double','double','double','char','char','double','logical'};
%questo-...(poi occorre salvarlo)
end
function SaveButtonPushed(app, event)
app.UITableCellSelection();
Instrum_Tab=app.InstrumTab;
disp(Instrum_Tab)
Instrument=string(app.Setting.Instrument);
save(Instrument,'Instrum_Tab');
end
i add data in a table(row 35) and i save it (SaveButtonPushed)
But i see it's a char and not a double (in app.uitable i set :
app.UITable.VariableTypes={'char','char','double','double','double','double','char','double','double','double','double','char','double','double','double','double','char','char','double','logical'};)

I suggest that you attach app.UITable in a .mat file so we can examine it.

The .mat file doesn't contain a uitable object. It is just the table data as a cell array. You need to do,
T=app.UITable;
save filename.mat T

Instrument=app.Setting.Instrument; % try without converting the imported data to string
save(Instrument,'Instrum_Tab');

"Unrecognized property 'VariableTypes' for class 'matlab.ui.control.Table'."
Indeed, there is no such property. Why did you put it in there? Perhaps you meant to have,
app.UITable.ColumnFormat={'char','char','numeric','numeric','numeric','numeric',...
'char','numeric','numeric','numeric','numeric','char',...
'numeric','numeric','numeric','numeric','char','char','numeric','logical'};

yes correct...however I can't convert a 'char' to numeric..I still have the problem
The screenshot you are showing is a view of Instrum_Tab in the Variable Editor, not in an app uitable. The reason '50' appears as a char vector is because you entered it in the Variable Editor that way, and there is no influence the app has over that.
Presumably you meant to enter it in the UITable.
