Error using closereq while trying to capture a Data Matrix

I'm using a live script that gets it data from a table generated in a UI and generates a matrix after closing the UI figure.

All was working good until suddenly I go the message:

Error using closereq

Error while evaluating Table DeleteFcn.

Here is my code:

core_data = zeros([rows, cols]);            %   Rows and cols are defined using the slider.



%% Make Table
uT = uitable;

uT.ColumnName = {'Flux' 'Frequency' 'Power'};
uT.Position = [100 100 275 260];

uT.Data = core_data;
uT.ColumnEditable = true;


uT.DeleteFcn = @getTableData;

waitfor(uT);                                 %   Waits for table to close

the offensive line is at uT.DeleteFcn = @getTableData

Do someone knows how to fix this??

And, how do you define getTableData? I can't reproduce the issue only with the code you shared.

If you would, it's best to share the live script with the issue.

Hello Angelo, thank you for your response.

I used the following link for this action:

I experimented with Approach 1 and all works fine, but table had not header and didn't look so well, so I used the recommened Approach 2,

Not capturing the data and giving the mentioned error.

I'm just stuck on that by the moment (now I'm keeping using Approach 1 "openvar").
