Hello Aleksey,
To print a figure to a PDF in vector format, please consider the following suggestions:
1. Specify the graphics renderer as '-vector' while using the 'print' function as detailed in the documentation here: https://www.mathworks.com/help/matlab/ref/print.html#bukyb6e-1-renderer
2. Call the exportgraphics function. Specify an .eps, .pdf, or .emf file extension and set the 'ContentType' option to 'vector'. This function captures content that is tightly cropped around plots, and it does not create full-page output. For example, create a plot and save the contents of the current figure as a PDF file containing vector graphics.
plot([0 3 2 4 1]);
exportgraphics(gcf,"myplot.pdf","ContentType","vector")
3. Consider using this function available on File Exchange SaveFigure: Matlab vector figure export
I hope this accomplishes your task.
