Adding a column to a UITable and then using it.

After a few hours of trying I finally was able to add a column to a UITable

A = zeros([1 size(app.StimInputTable.Data,1)]);
app.StimInputTable.Data.Var4 = A'; % Have to make A a column vector!
for ii = 1:size(app.StimInputTable.Data,1)
     app.StimInputTable.Var4(ii) = ... 
          app.StimInputTable.Data.Var3(ii)/app.StimInputTable.Data.Var2(ii);

But now...

assigning a value to Our new column Var4 gives me

Unrecognized method, property, or field 'Var4' for class 'matlab.ui.control.Table'.

It know what app.StimInputTable.Data.Var3(ii)/app.StimInputTable.Data.Var2(ii);

is so now put it in Var4! How hard can that be?

K>> app.StimInputTable.Data

ans =

4×4 table

Var1 Var2 Var3 Var4

____ ____ ____ ____

4 5 0 0

5 4 1 0

2 3 2 0

3 2 5 0

I can do it 1 row at a time from theCommand window:

K>> app.StimInputTable.Data

ii = 1 (etc)

K>> app.StimInputTable.Data.Var4(ii) = app.StimInputTable.Data.Var3(ii)/app.StimInputTable.Data.Var2(ii)

Although the "answer" I get is my whole

app =

MouseOdor4 with properties:

MouseOdor: [1×1 Figure]

all the properties of the whole app I won't bore you with

K>> app.StimInputTable.Data

ans =

4×4 table

Var1 Var2 Var3 Var4

____ ____ ____ _______

4 5 0 1

5 4 1 2

2 3 2 0.66667

3 2 5 2.5

Look it worked!

Next step if you don't mind anwering is to sort the table by the Var4 column

BTW I tried addvars() for a while as help said to do but never got that to work following all the examples the best I could

app.StimInputTable.Data.Var4 = app.StimInputTable.Data.Var3./app.StimInputTable.Data.Var2;
%                 ^^^^^ you were missing the .Data

[Alessandro Livi]

Thanks I saw that after I pasted the code here. I fixed that and now it runs through that callback and then quits running in the App Designer debugger with NO errors either in the command window nor in App Designer.

My program continues to run OK but I can no longer debug.

[Voss]

So no breakpoints are being triggered?

[Alessandro Livi]

Added some string stuff which completes but now when I exit the callback it halts here so maybe that is a clue?

methods (Access = protected, Sealed = true)

function newCallback = createCallbackFcn(app, callback, requiresEventData)

if nargin == 2

requiresEventData = false;

end

ams = appdesigner.internal.service.AppManagementService.instance();

newCallback = @(source, event)executeCallback(ams, ...

app, callback, requiresEventData, event);

end

Is there some magic I have to do at the end of a callback function?

[Voss]

No magic required. What is the problem you are describing?
