How to save a figure in MATLAB from the command line?

Question

Is there a command in MATLAB which allows saving a figure in FIG or JPEG or both formats automatically?

Answer 1

Use saveas:

h=figure; plot(x,y,'-bs','Linewidth',1.4,'Markersize',10); % ... saveas(h,name,'fig') saveas(h,name,'jpg') 

This way, the figure is plotted, and automatically saved to '.jpg' and '.fig'. You don't need to wait for the plot to appear and click 'save as' in the menu. Way to go if you need to plot/save a lot of figures.

If you really do not want to let the plot appear (it has to be loaded anyway, can't avoid that, else there is also nothing to save), you can hide it:

h=figure('visible','off') 

Answer 2

When using the saveas function the resolution isn't as good as when manually saving the figure with File-->Save As..., It's more recommended to use hgexport instead, as follows:

hgexport(gcf, 'figure1.jpg', hgexport('factorystyle'), 'Format', 'jpeg'); 

This will do exactly as manually saving the figure.
