How to close neural network training dialog in 2022a

Hello everyone,

in 2022a the nntraintool command has been removed

Citation:

R2022a: nntraintool has been removed

Errors starting in R2022a

nntraintool has been removed. To train a network and open the training window, use train instead.

The documentation only mentions that opening it is now done via the "train" command. It does however not mention how to replace

nntraintool('close')

in 2022a.

Can anyone point me to some code on how to programmatically close the traintool after training? Or is this function simply lost?

Thanks in advance.

Referring to this question, this can be done using the following command:

delete(findall(0))

This is because the ‘HandleVisibility’ is set to ‘off’ for these plots by default.

Thank you for the response.

Yes, this approach indeed helps in 2022a.

Unfortunately I need to maintain compatibility with 2020b for at least some months as not all my colleagues can upgrade right now. Now I find myself in the dilemma that either solution works only in one of those releases. I can of course try to add some switch statement checking for the matlab release and remove it in the future; But this appears to me not a very clean solution.

If there is no better (more window-selective or version-compatible) solution I will gladly accept your answer, because it is indeed helping, but I will give others some more days in the hope my additional requirements that I did not mention in the beginning could also be fulfilled.

This is what I came up with, thanks to your answer:

function close_traintool()
    matlab_version = regexp(version("-release"), "(\d{4,4})(a|b)", "tokens", "once");
    if str2double(matlab_version{1}) >= 2022
        delete(findall(0));
    else
        nntraintool('close');
    end
end
