Matlab - How to save view configuration of matlab neural network

I am trying to configure a neural network using matlab and newff command.

After that, I am trying to visualize my created configuration using the view command.

x = view(net);

How can I save the displayed window to a .png file? I have tried with saveas(x, 'figure.png', 'png') but it won't work? Do you know how can I do that from code?

Solution

  • The created window is a pure Java figure (not MATLAB Handle Graphics). Try this to capture it:

    %# neural net, and view it
net = feedforwardnet(5);
jframe = view(net);

%# create it in a MATLAB figure
hFig = figure('Menubar','none', 'Position',[100 100 565 166]);
jpanel = get(jframe,'ContentPane');
[~,h] = javacomponent(jpanel);
set(h, 'units','normalized', 'position',[0 0 1 1])

%# close java window
jframe.setVisible(false);
jframe.dispose();

%# print to file
set(hFig, 'PaperPositionMode', 'auto')
saveas(hFig, 'out.png')

%# close figure
close(hFig)
