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'};)

this:
app.UITable.VariableTypes={'char','char','double','double','double','double','char','double','double','double','double','char','double','double','double','double','char','char','double','logical'};
is not correct
i see error
"Unrecognized property 'VariableTypes' for class 'matlab.ui.control.Table'."

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'};

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.
