Hi,
in my incoming work on implementing Loop Quantum Gravity I will need
a 15-dimensional sparse matrix (or tensor) to store the quantum
gravity data in a 15-dimensional basis. The data is very sparse, most
of it are zeros. But if I tried to use a regular vector> 15 times
I will quickly run out
Good move, congrats!

Wow, it looks like this is a nice test case with an exact solution.
Maybe it's worthwhile to add this to eigen tests?

yeah. I did a couple of small merge requests. Depending on what my
software YADE will need, I will do some more

I suggest to move forward, and use C++17. There is no reason to
stick with old libraries.
If you prefer to keep for a year or two the ability to compile with
C++14, then place such obsolete code inside some #ifdef #else #endif,
so that more efficient code is generated with C++17 and less

Whoa! That's surprising. I am really glad that Eigen
Hi,
when I was writing tests for my NumTraits implementation I suppose found an
inconsistency:
Eigen::internal::random() returns in range (-1,1)
Eigen::internal::random() returns in range (-1,1)
Eigen::internal::random() returns in range (-1,1)
Eigen::internal::random() returns in range (0,1)

ognize that they are out
of date, which resulted in super-weird build errors. I found out that
ccache is much more robust and reliable.

We moved YADE to gitlab about a year ago, and I found that the default
merge request merging with a rebase before (clicking the green
"rebase" button) works the best for us.
Especially important to keep all the commits fully compilable and
working. Which fortunately is possible thanks to CI. Then
Hi,
I am developer of YADE, https://gitlab.com/yade-dev and I want to add
high precision support in our entire codebase. Unfortunately I have
been getting eigen segfaults in my tests. More about that in another email.
I want to talk a little about your gitlab migration :)
