%% maximizeFigure
%
% Maximizes the current figure or creates a new figure. maximizeFigure() simply maximizes the
% current or a specific figure
% |h = maximizeFigure();| can be directly used instead of |h = figure();|
%
% *Examples*
%
% * |maximizeFigure(); % maximizes the current figure or creates a new figure|
% * |maximizeFigure('all'); % maximizes all opened figures|
% * |maximizeFigure(hf); % maximizes the figure with the handle hf|
% * |maximizeFigure('new', 'Name', 'My newly created figure', 'Color', [.3 .3 .3]);|
% * |hf = maximizeFigure(...); % returns the (i.e. new) figure handle as an output|

Questo non deve essere contrassegnato come duplicato. La domanda di riferimento si riferisce all'impostazione di una figura in una dimensione specifica, in pixel. Questa domanda (e risposta) imposta una figura alla dimensione massima, senza riferimento al numero di pixel coinvolti. – Pursuit
