Radonirinaunimi / cmpx-spfunc

Library for computing various special functions with complex arguments

cmpx_spfunc

Library for computing various special functions (such as Gamma, Hypergeometric, Bessel, incomplete Beta, etc.) with complex arguments. While other libraries only accept a few arguments to be complex (or none), cmpx_spfunc provides functions whose arguments are all defined in terms of complex values (this sometimes requires analytic continuation).

Install dependencies

For the compilation, the code relies on meson and ninja. To install meson and ninja, just run:

pip install -r requirements.txt

In addition, cmpx_spfunc relies on a third party C++ library complex_bessel.

Compile & run the code

Thanks to meson, compiling the code is straightforward:

git clone https://github.com/Radonirinaunimi/cmpx-spfunc.git
cd cmpx-spfunc
meson setup builddir
cd builddir
meson compile

This will generate an executable called test_spfunc. Then, to run the code, just type the followinc command:

./test_spfunc

Every time changes are made, the code can be re-compiled by just running meson compile inside the builddir directory.

System-wide installation

Finally, in case one wants to install the header files and library system-wide, this can be done by running the following:

meson install

This, by default, will install the header files in /{prefix}/include/cmpx_spfunc and add cmp_spfunc.pc to the PKG path.
