when I use app designer， it tells me error of 'Value' must be a character vector or a string scalar.

I have write a script,I want to get tabulate(u), "u" is a matrix （200x1 double）。the result is as follows:

Value Count Percent

1 0 0.00%

2 0 0.00%

3 0 0.00%

4 0 0.00%

5 0 0.00%

6 91 45.50%

7 0 0.00%

8 109 54.50%

Then I want to do the script in app designer,I creat a edit field (text) which is used to display the tabulate.

but it always error:

z1=tabulate(u);

app.lousunEditField.Value=z1

then it tells "Error using matlab.ui.control.EditField/set.Value (line 98)

'Value' must be a character vector or a string scalar."

I have tried the string、num2str,it still doesn't work.

Is it a Numeric Edit field, or is it a Text Edit field?

Hi,

z1 is a table, and Value doesn't accept tables. You can create a UITable component and just assign z1 to it

app.UITable.Data = z1;

If you insist on EditField components, index into the table using curly brackets.

After I type

z1=tabulate(u);

app.lousunUITable.Data = z1; [error][1]Unrecognized method, property, or field 'UITable' for class

'lousunshibie'.

app.lousunEditField.Value={app.UITable.Data}

Anything wrong?

[Walter Roberson]

That error message would suggest that your actual code is

app.lousunshibie.UTTable.Data = z1;

rather than what you posted.

I still want to know more about how to index into the table using curly brackets.

THANKES!
