Example of Compiling and Executing the File

  1. Compile the file.
    1
    g++ test.cpp -o test -L /usr/local/kml/lib/ -lkfft -lkfftf -L /usr/local/kml/lib/kvml/single -lkvml -lkm -lm -L /usr/local/kml/lib/kblas/locking -lkblas -L /usr/local/lib/HMPP -lHMPP_signal -lHMPP_core -lpthread
  2. Execute the file.
    1
    ./test
