Display the part of the graph beyond the axis limit in Matlab

When I tried to manually adjust the axis limits of a graph, Matlab will automatically cut off the part of the graph that is beyond the axis limits. This didn't happen before (and before means 2014a or earlier versions). I took a little while to find the cure. Just try the following scripts.

ax = gca;
ax.Clipping = 'off';

Change default mail app in OS X

Here is the steps to change default mail app in OS X:

1. Open Mail app.
2. Select Preferences -> General. Under "Default email reader", select your preferred mail app.

I am running into a problem by following the steps: the default email reader changes back to the original mail app seconds after I made the change. Here is the solution that works for me. Open terminal. Copy and paste the following script.

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -all local,system,user

Then try step 1-2 again, and it won't change back again!

Hierarchical construction of bounded solutions to divU = F

• This is a joint work with Eitan Tadmor.
• It has been published in a chapter of the book Nonlinear Partial Differential Equations, Volume 7 of the series Abel Symposia doi:10.1007/978-3-642-25361-4_14.

Here is an outline of the paper.

We propose a numerical approach to solve the minimization problem of the hierarchical decomposition introduced by Tadmor [Ta15], using duality to treat with $$L^{\infty}$$ norm inside. And then generate the uniformly bounded solution of $$\nabla\cdot U = F$$ in actual computation.
