These executables include LAPACK subroutines.
The run times are roughly 6 times faster on FACTOR and 40% faster on FILL times.

I added a command line argument feature.
Input and output file names can be entered with command line
Example: nec2dxs64LP5k0 elevrad.inp elevrad.txt

If you use 4nec2, you can rename these files to remove the "32LP" in the file name.
Then you can simply copy them over the files in 4nec2 exe directory.
Be sure to make backup copies of the original exe files in case bugs are
discovered with these executables.

Report bugs to jelanier@chemroc.com

Enjoy,
