wrong type variable in uitable

     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.

[Luca Re]

only line 35 was added using the editor and then saved

[Matt J]

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

[Luca Re]

[Luca Re]

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'."

@Luca Re

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

Answer 1

[Matt J]

"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'};

[Luca Re]

yes correct...however I can't convert a 'char' to numeric..I still have the problem

[Matt J]

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.
