kuramoto

An efficient C implementation of the standard Kuramoto coupled oscillators system

with C and Matlab interfaces. Simulations using the Euler and classic Runge-Kutta ("RK4") methods are available. There are C and Matlab programs to demonstrate usage of the interfaces to the kuramoto library.

Building and installation

You will need the Make build tool installed on your system, and the Matlab mex and makemex executables (in the bin directory of your Matlab installation) on your system executable path ¹.

To build and install the kuramoto shared library, in a terminal navigate to the kuramoto root directory and run

make -C C/lib && sudo make -C C/lib install

This builds, and then installs the library. The default installation directory is /usr/local/lib (you will need admin privileges for this). You may specify an alternative installation path by setting the PREFIX environmental variable before running make install.

To build the C demo, run

make -C C/demo

and to build the Matlab interface, run

make -C Matlab

Testing

To test the C interface, try running

./kuramoto demo

and

./kuramoto audio

in the kuramoto/C/demo directory. To test the Matlab interface, run

kuramoto_demo

at the Matlab prompt in the kuramoto/Matlab directory.

Contributing

If someone would like to contribute a Python (NumPy) interface, please contact the maintainer. This should be reasonably starightforward using ctypes.

Footnotes

1. Building/installing targets a POSIX environment. Tested with gcc (Linux 64-bit), mingw-w64/MSYS2 (Windows 64-bit) and Clang/LLVM (macOS). Note that MSVC (still) does not fully support the C99 standard, so may be problematic. ↩
