Hello. In Mathematica, I can use the following Mathematica code to generate a text outline path, and get the 2D points of the text outline. Can I do same thing in MATLAB?

Thanks a lot!

% Mathematica code (not MATLAB):
text = Text[Style["A", Bold]];
tg = DiscretizeGraphics[text, _Text, MaxCellMeasure -> 0.005]; 
pts = MeshCoordinates[tg];
pts = pts[[Last[FindShortestTour[pts]]]];

在 MATLAB Online 中打开

Try this:

x = linspace(0, 4*pi, 50);
y = sin(x);
plot(x, y, 'b.-', 'MarkerSize', 15);
hold on;
for k = 1 : length(x)
	textHandle = text(x(k), y(k), ' Moving text', 'Color', 'r', 'FontSize', 12, 'FontWeight', 'bold');
	pause(0.2);
	% Now erase the text to prepare for next time.
	delete(textHandle);
end
