ASA172
Generation of all multi-indices in a given range

ASA172 is a FORTRAN77 library which simulates the behavior of a nested set of FORTRAN Do-Loops in generating all multidimensional indices in a given range.

ASA172 is Applied Statistics Algorithm 172. Source code for many Applied Statistics Algorithms is available through STATLIB.

Languages:

ASA172 is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.

Source Code:

• asa172.f, the source code.
• asa172.sh, commands to compile the source code.

Examples and Tests:

• asa172_prb.f, a sample calling program.
• asa172_prb.sh, commands to compile and run the sample program.
• asa172_prb_output.txt, the output file.

List of Routines:

• REVERS reorders the subscript vector, if required.
• SIMDO generates multi-indices, simulating nested DO-loops.
• TIMESTAMP prints out the current YMDHMS date as a timestamp.
