fortran_lib

This Fortran library provides basic data structures, algorithms and some handy utilities, which are applicable for almost all of intrinsic types.

Compilation

# fortran_lib should be cloned rather than downloaded as a tar file
# because `git ls-files` is used in the build process
git clone https://github.com/kshramt/fortran_lib
cd fortran_lib
make

Compilation may fail with internal compiler error: Killed (program f951) if your computer does not have enoguh memory (about 3 GB for GFortran).

*.f90.erb files are preprocessed by eRuby and cpp during the compilation. Preprocessed pure Fortran code is also available at https://github.com/kshramt/fortran_lib_expanded and https://bitbucket.org/kshramt/fortran_lib_expanded.

Dependencies

• Git
• GNU Make 3.82 or newer
• GFortran 4.9 or newer
• Ruby 1.9 or newer
• BLAS and Lapack

Notes for Mac users

GNU version of basic commands (sed, awk, getopt and so on) are assumed to be installed. For example, script/make_include_make.sh does not work with BSD-sed. Please install GNU Coreutils and GNU version of other necessary commands.

Useful Codes

bin/etas_solve.sh and release/bin/etas_solve.exe

These programs estimate the ETAS parameters. Please run

bin/etas_solve.sh --help

for the details. example/etas_solve/README.md describes output format of etas_solve.exe.

Example

bin/etas_solve.sh \
   --t_normalize_len=1 \
   --m_for_K=6 \
   --t_pre=0 \
   --t_begin=0 \
   --t_end=1000 \
   --data_file=example/etas_solve/catalog.tsv |
   release/bin/etas_solve.exe

bin/etas_intensity.sh and release/bin/etas_intensity.exe

These programs calculate the intensity function given data and parameters. Please run

bin/etas_intensity.sh --help

for the details.

bin/etas_log_likelihood.sh and release/bin/etas_log_likelihood.exe

These programs calculate log likelihood, gradient and Hessian for given data and successive parameter sets. Please run

bin/etas_log_likelihood.sh --help

for the details.

example/etas_solve/make_catalog.py

This script generates a synthetic catalog for the temporal ETAS model.

release/src/ad_lib.f90

This module contains types and routines for automatic differentiation up to second-order derivatives with 1, 2 and 5 independent variables.

release/src/comparable_lib.f90

This module contains almost_equal.
