call the exportgraphics function and set the 'ContentType' name-value pair argument to 'vector'. For example, create a bar chart, and save the figure as a PDF file containing vector graphics. All embeddable fonts are included in the PDF.

bar([1 11 7 8 2 2 9 3 6])

f = gcf;

% Requires R2020a or later

exportgraphics(f,'barscalable.pdf','ContentType','vector')
