This package includes all the source codes of the well-known book:

Numerical Recipes in C: The Art of Scientific Computing (2nd Edition, 1997)
by William H. Press, Brian P. Flannery, Saul A. Teukolsky, William T. Vetterling

Software version 2.08

https://numerical.recipes/

Many things have been changed, e.g., all the subroutine names. This version of the code is more portable than the original one.

It works in Linux. It may also works in Windows (read (9)).

You need a C compiler, e.g., gcc or icc. You also need the ar command.

There are two optional commands, i.e., timeout and md5sum, where timeout is only for running tests, and md5sum is for calculating MD5 cryptographic checksums. They are required in the script sh.make.dev.

If you dont like timeout or md5sum, use sh.make instead of sh.make.dev.

In Linux terminal, perform the command:

bash sh.make.dev
bash sh.make

Then, read the text message on your screen to know how to use.

For example, to run everything, you can do like this:

bash sh.make.dev  all 
bash sh.make  all 

The latter command compiles all the codes in src/, prepares the header files, i.e., src/*.h, creates the library libNRinC.a, compiles all programs in test/ and executes them right away.

You can see how to compile and link your program to the library. You can change everything inside the script sh.make.dev.

One more thing: all real numbers are compiled with double precision (i.e., 8 bytes, double) instead of single precision (4 bytes, float) as in the original version. Make your own setting in src/nrc_types.h.

Enjoy coding!

(1) If you dont have timeout, check: https://command-not-found.com/timeout

(2) If you dont have ar, check: https://command-not-found.com/ar

(3) If you have no gcc, check: https://command-not-found.com/gcc

(4) If you want to try with icc in , e.g., Debian, then follow these steps:

wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | gpg --dearmor | sudo tee /usr/share/keyrings/oneapi-archive-keyring.gpg > /dev/null

echo "deb [signed-by=/usr/share/keyrings/oneapi-archive-keyring.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.list

apt-get update 
apt-get upgrade -y 
apt-get install -y intel-oneapi-compiler-dpcpp-cpp-and-cpp-classic

(5) If you have no md5sum, check: https://command-not-found.com/md5sum

(6) You can remove timeout and md5sum from the script sh.make.dev since they are not so essential.

(7) Use the new script sh.make if you dont like timeout or md5sum.

(8) Tests now can run smoothly and properly. Many things were made to test/, e.g., adding input files, correcting formats for the scanf and fscanf routines, etc.

(9) To run in Windows, you can install cygwin, then bash, gcc, and ar. The script sh.make should work.
