Q.N 1)

I have a matrix say Z whose size is (4,1). I now want to copy it to a column 4 of my table.

I used the commmads as below but nothing worked.

app.UITable2.data(:,4) = Z ; (It did not work).

app.UITable2.data(:,4) = num2cell(Z ) ; (It did not work).

Q.N 2)

In my table, i want to convert all column 3 cells to a dropdown format which displays Yes and No.

i used the code ,,,,app.UITable.column(3) = categorical({'Yes',{'Yes','No'}); but did not work. Can somebody help me with both the questions.

Thanks.

Does your table have more then 4 rows? Try this

app.UITable2.data(1:4,4) = num2cell(Z);

To display a dropdown menu in the column cell, you can do something like this

app.UITable.ColumnEditable(4) = true;
app.UITable.ColumnFormat(4) = {'Yes','No'};

"Unable to perform assignment because the indices on the left side are not compatible with the size of the right side." error of this kind appears if i use the above command.

Can you show the output of

disp(app.UITable.ColumnEditable)
disp(app.UITable.ColumnFormat)

in command window.
