How do I change the Matlab Desktop font preferences using commands?

I want to be able to create a shortcut which changes my Matlab Desktop (layout, font sizes, etc..) so that I can have a "Presentor" version of Matlab when I am presenting in a conference room, or to others, and a "Working" version of Matlab Desktop for when I am working..

To display MATLAB on a screen for a public , I run this function :

function largefonts(state)
% LARGEFONTS ON   Turn on large fonts
% LARGEFONTS OFF  Turn off large fonts
% LARGEFONTS      Toggle large fonts
% LARGEFONTS FS   Turn on large fonts, with font size FS.  

% Get largefonts preferences
FS = getpref('LargeFonts');
if isempty(FS)  % Create preferences if necessary
    setpref('LargeFonts','State','Off'); 
end;

% Parse input arguments
if nargin==0            % Toggle state
    state = lower(getpref('LargeFonts','State'));
    switch state
        case 'on'
            state = 'off';
        case 'off'
            state = 'on';
    end;
elseif ~isstr(state)  % Specified font size.  Turn on.
    FontSize = state;
    state = 'on';       % Turn on
else                    % Go to specified state
    state= lower(state);
end;

if ~exist('FontSize','var')
    FontSize = 16;      % Default size for large fonts
end;

%%Toggle font sizes
switch state
    case 'on'
        % Big-
        com.mathworks.services.FontPrefs.setCodeFont(java.awt.Font('Monospaced',java.awt.Font.BOLD,FontSize))
        com.mathworks.services.FontPrefs.setTextFont(java.awt.Font('SansSerif',java.awt.Font.BOLD,FontSize))
        setpref('LargeFonts','State','On');

      case 'off'
          % Small-
          com.mathworks.services.FontPrefs.setCodeFont(java.awt.Font('Monospaced',java.awt.Font.PLAIN,10))
          com.mathworks.services.FontPrefs.setTextFont(java.awt.Font('SansSerif',java.awt.Font.PLAIN,10))
          setpref('LargeFonts','State','Off');

end;

Does this set the font property, such that you have to restart MATLAB to activate it?

Dear @Aurelien Queffurust, I like your code very much.

Font:

F = java.awt.Font('Arial', java.awt.Font.PLAIN, 16);
matchClass = 'javax.swing.JTextArea$AccessibleJTextArea';
cmdWinDoc  = com.mathworks.mde.cmdwin.CmdWinDocument.getInstance;
cmdWinListener = cmdWinDoc.getDocumentListeners;
for iL = 1:length(cmdWinListener)
  if isa(cmdWinListener(iL), matchClass)
    cmdWinListener(iL).setFont(F);
    break;
  end
end

Layout:

desktop = com.mathworks.mde.desk.MLDesktop.getInstance;
desktop.restoreLayout('Command Window Only');
pause(0.1);  % This might take some time

You can save the layout under an individual name. Note that the restoreLayout function is case-sensitive.

I'm going to add this to FEX: CmdWinTool. This tool can be used to create a lean desktop also.

You know what, Yair, I bet you gonna love this extraordinary File Exchange function called

cprintf

Check it out here:- http://undocumentedmatlab.com/blog/cprintf-display-formatted-color-text-in-command-window/

Till today it still amazes me the length the author of that file went to achieve that.

This will not help, because the OP wants to change the general appearence of all output.
