Hi,

I'm using the App Desiner to write an optimization model.

I'm facing this problem can someone help? I also created a matrix with zeros (matrix=zeros(4,4)) and stored it in 'zero.mat', which is of a class:double.

       
        function import(app,event) 
            if event.Indices(2)==3 && event.NewData>0
                data=app.UITable.Data;
                neu=event.NewData;
                data(event.Indices(1),1)={neu};
                app.UITable.Data=data;
            end
        end

import is a Matlab-supplied data input function; your function will alias that. You might consider changing names to something that doesn't conflict.

As to the error, you wrote

data(event.Indices(1),1)={neu};

that specifically turned event.NewData into a cell, whatever the new data were; then you tried to write that in the next line to a UITable. Remove the {} as first guess...
