Hi,
I would like to add a neural network graphical diagram to my live script. Unfortunately command view produces new window instead of adding diagram to the live script.
To be clear, this code (in a Live Editor) attaches output of plot command directly to the live script, but does not include neural network diagram:
plot(1:10)
net = patternnet;
view(net)

You are experiencing this problem because the view(net) function does not output a figure, it outputs a Java object. I don't know a perfect work around, but you can try this:
function newView(net)
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();
I found this solution here. With this, you can have your network as a figure, and it will appear in the livescript. The only remaining issue is that the undocked figure window doesn't close once it has been plotted in the livescript, which is peculiar.

Thank you for your answer. I've modified it a little bit, and now figure window can be closed automatically:
function outH = newView(net)
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, 'Parent', hFig, 'units','normalized', 'position',[0 0 1 1])
%# close java window
jframe.setVisible(false);
jframe.dispose();
% capture figure as a frame
F = getframe(hFig);
% close current figure
close(hFig)
% display the captured image data using imshow
hFig = figure('Menubar','none', 'Position',[100 100 565 166]);
axes('units','normalized', 'position',[0 0 1 1])
imshow(F.cdata)
axis off
% return handle if needed
if nargout == 1
outH = hFig;
end
