Then include it.\n\n### Usage as a pre-built library\n\nCompile the library via CMake giving `-DGF11_BUILD_LIBRARY=ON`.\n\n### Testing\n\nIn `tests/`, there is a code to check the relative and absolute difference between\n`greens_functions` and `greens_functions11`. The results are put on `stdout`.\n\nIt also compares the time took. The results are put on `stderr`.\nTo check correctly, it is recommended to turn `-O3 -march=native -mtune=native`\nin `greens_functions`.\n\n## Benchmark Results\n\nThe following micro benchmarks does benchmark and also error checking.\nSo the durations include the time took to store the data into vector and the\nreal efficiency might differ.\n\n| function                     | gf98           | gf11                         |\n|:-----------------------------|:---------------|:-----------------------------|\n| 2DAbsSym.drawTime() x100'000 | 1.54186  [sec] | 0.367498 [sec]: ~4.2x faster |\n| 2DAbsSym.drawR()    x100'000 | 1.56546  [sec] | 0.37903  [sec]: ~4.1x faster |\n| 3DAbsSym.drawTime() x100'000 | 0.325472 [sec] | 0.118635 [sec]: ~2.7x faster |\n| 3DAbsSym.drawR()    x100'000 | 0.667269 [sec] | 0.393544 [sec]: ~1.7x faster |\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fecell%2Fgreens_functions11","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fecell%2Fgreens_functions11","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fecell%2Fgreens_functions11/lists"}
