Export figure to Vector Graphics

Finally, as of 2020….

exportgraphics(spm_figure('FindWin','Graphics'),[pth,'mean.pdf'],'ContentType','vector')

erxport_fig used to be ok for this. Print had to use painters option

print(spm_figure('FindWin','Graphics'),'-dpdf','-painters','-noui',...

[pth,'mean.pdf'])
