If plugins are not available, you can still try to edit your theme and add the second code block from this page http://docs.mathjax.org/en/latest/configuration.html to your header.php (in the ). ]]>

Nevertheless, this does not solve your figure/TikZ problem, it makes formulae look nicer.

thanks for the advertisment!

@ Why we did not cite the other paper: We did not know about it in June when we submitted our draft.

timeline from my point of view:

– 21-22 /09/2012 (Graz: Trends in Optimization and Control Colloquium) O. Scherzer: Tube Methods for Total Variation Minimization.

Otmar presented the explicit TGV-solution for characteristic function.

– 17/06/2013: paper submitted to Communications in Math. Science

– 20/09/2013: Mr. Papafitsoros sent his draft to O. Scherzer. Because our paper got cited there ..

– 27/09/2013: we put our paper online on ArXiv

@ similar pictures: That’s a good thing: The solution seems to be correct ;)

Greetings from Grenoble,

Christiane

I am a novice in matlab. I have an image and I want to compute the gradient and divergence of the image. I was till recently using the gradient command. However I found that it is painfully slow. So I read your blog. Can you tell me the gradient command in matlab does forward difference, backward difference or central difference ?

An can you give me an idea regarding what should I use instead of that so as to make it faster ?

Thanks in advance.
