MATLAB: How to Assign an Axes Object to a struct

axesfigurestruct

It seems that MATLAB automatically assign h2Axes to struct G, not hAxes. How can I specifically assign hAxes to struct G?
hAxes = axes('NextPlot', 'add', 'XLim', [0, 20], 'YLim', [-1, 10], 'Position', [0 0 0.5 0.5]);
h2Axes = axes('NextPlot', 'add', 'XLim', [0, 20], 'YLim', [-1, 10], 'Position', [0.5 0.5 0.5 0.5]);
W = 4;
Y = 0;
H = 8;
for i = 1 : 3
  X = i.* W;
  R = rectangle;
  R.Position = [X Y W H];
  G(i).r = R;
end

Best Answer

hAxes = axes('NextPlot', 'add', 'XLim', [0, 20], 'YLim', [-1, 10], 'Position', [0 0 0.5 0.5]);
h2Axes = axes('NextPlot', 'add', 'XLim', [0, 20], 'YLim', [-1, 10], 'Position', [0.5 0.5 0.5 0.5]);
W = 4;
Y = 0;
H = 8;
for i = 1 : 3
  X = i.* W;
  R = rectangle('Parent', hAxes);
  % Or:
  % R.Parent = hAxes;
  R.Position = [X Y W H];
  G(i).r = R;
end
