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<vector<....>> 15 times
I will quickly run out of memory.
So, does libeigen offer such data type?
best regards
Janek Kozicki
