I'm looking for a software which may help me to both take notes and draw graphs during university lectures. It must have the ability to switch between texts and graphs, add other formats such as Office related format and pdf. Also, the the graphs should be easily tunable (preferably on the fly) and of course, shareable. Being able to draw matrices and operate with them would be great too.
I can't seem to find an application/software for laptop which makes all of those easy in an economics related setting. Any idea?
Thanks a lot
