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 -- Janek Kozicki, PhD. DSc. Arch. Assoc.
