I saved a file with
set(gca, 'LooseInset', get(gca, 'TightInset'));
set(gcf, 'PaperPositionMode', 'auto');
saveas(gcf, filename, 'epsc');
but it had too much white space. It was 1.2mb in size.
So I saved it with
exportgraphics(gcf, filename, 'ContentType', 'vector', 'Padding', 0);
This resolved the white space issue, but it was 79mb in size.
Is there a way to save the figure without the huge jump in file size? I am trying to save a complex phase portrait. I want to save several of them, so I don't want to have to do the cropping in an external program. Thanks.

I'm sure you have identified the problem. I adapted some code from file exchange to generate my image and presumably it is raster rather than vector. Thanks.
