how to save the NN training result properly so that next time using "nntraintool" can reload the old history

Hello,

after training a NN model, when I close the GUI nntraintool and reopen it again, it will load automatically the training procedure and result data again.

But although I saved the workspace, but when I close matlab and reload the space, and open nntraintool, it can not load the training procedure and data.

How can I save the data correctly so that next time when I open nntraintool it will show me the same view as after the training?

Thanks

I found some turn around solution.

if I do

[net, tr] = train(net, x, t);

plottrainstate(tr)

same for plotfit | plotperform | plotregression

It will give me the plots as in the nntrailtool.
