Benchmark of expression templates libraries [eigen, blaze, fastor, armadilloa, xtensor]
To compile the benchmark download all the aforementioned libraries first and then
make all EIGENROOT=... BLAZEROOT=... FASTORROOT=... ARMAROOT=... XTENSORROOT=... CXX=g++/clang++/icpc/...
where ... implies path to the library. To run the benchmark
make run N=size
where size=100,150,200 is the grid size.
