Usage: ./ForcedRandom [OPTIONS]

Options:
  -h,--help                   Print this help message and exit
  -n UINT REQUIRED            Number of points
  -d UINT                     UNUSED ! Here for compatibility with others.
  -s,--seed UINT              UNUSED ! Here for compatibility with others.
  -m UINT [1]                 Number of pointsets
  -o,--out TEXT [out.dat]     Output file (format). {i} splits outputs in multiple files and token is replaced by index.
  --sparsity INT [8]          Sparsity coeff
  --matrixSize UINT [512]     Matrix Size (512, 1024, 2048. Other will be interpreted as 512)
  --silent                    Silence UTK logs
