How to display a cell content in MATLAB appdesigner

Hi everyone, I'm new on MATLAB and I'm having a issue on displaying a cell content in a Edit Field text box with the fonction/command celldisp in MATLAB appdesigner. I'm getting this error : Error using celldisp Too many output arguments.

Here is my code :

app.t = readtable("processus_dintegration.xlsx","VariableNamingRule","preserve");

app.NomsEditField.Value = celldisp(app.t{:,1});

Can anyone give a other fonction that can help me ?

Hey Elie Gédéon BIKIE,

The error occurs because the function used i.e. “celldisp” is meant for printing while here, it’s being used to assign output to an Edit Field.

I propose converting the cell array data into a single string that can be assigned t the Edit Field’s value property. Two common approaches are :

• Using “strjoin”: This function takes a cell array of strings and concatenates them into one string using a specified delimiter (for example, a comma and space, or even a newline).
• Using “sprint”: This function formats data into a string, and it is very handy if you want each cell element to appear on a new line.

For example :

• If you want comma-separated list :

    app.EditField.Value = strjoin(data.Fruit,’, ‘);  

• If you want each element on its own line:

    app.EditField.Value = sprintf(‘%s\n’,data.Fruit{:}); 

Below are some documentation links that will help you further :

Hope this helps. Thanks.

app.EditField.Value = strjoin(string(app.t{:,1}));
