I would like to define an editable 3*m matrix in app designer programmatically defined by users.

Once defined the parameter m in an editable field (numeric), the app automatically generates an editable 3*m matrix.

How can I do this?

I don't know how it is possible to define an editable matrix with predefined size.

If you know that last part, what exactly is your issue? It shouldn't be too difficult to have a callback that would use that method to create a matrix with the size your user supplies.

Hi,

I can comeup with the following workflow for your question:

In the callback of the editfield, you can create a table of size 3*m with editable property set.
Since the table is editable, user can therefore edit the fields.
You can create an apply button, and in its callback you can read the table data.

These documentation pages might help you work with tables:

Hope this will work for you!
