Save a .FIG as .JPG (syntax error?)

I currently have a string varible that updates my fig title and file names.

savefig(sprintf('%s - F vs V.fig', NAME))

But I also want to save a .JPG of the file too. I've tried:

saveas(sprintf('%s - F vs V', NAME),'.jpg')

Is there a syntax error I'm overlooking?

To save a jpg with saveas() you have to give a proper figure handle (at least gcf) as first argument and change '.jpg' to 'jpeg' as format specifier (no dot and including the "e").

e.g.:

clearvars, close all
clc

NAME = 'myFig'; % figure name and prefix of jpeg file name

fig = figure('Name', NAME); % creates figure and returns figure handle
plot(rand(100,1)) % plot some random data

saveas(fig, sprintf('%s - F vs V', NAME),'jpeg') % save as jpeg

However, i would recommend to use a vector graphics format or png instead of jpeg, because jpeg could contain ugly artifacts.

+1 clear advice, good recommendation to use PNG.

Of course a complete list of supported format specifiers (e.g. jpeg) is in the documentation:

saveas(gcf,sprintf('%s - Title).png', NAME))

I worked it out! Thank you!

You are welcome. Please consider to substitue gcf by a figure handle returned from the figure() command. gcf can become very confusing when dealing multiple figures or if you have user interaction.
