A (mostly) poorly written implementation of the FTLE algorithm for my dynamical systems final project. To compile the C files, you need OpenMP and gcc. I compile them on MacOS using
gcc-8 -fopenmp -o flow flow_map.c
and use Matlab to run the .m script. There is also a standalone C file called ftle.c which computes the flow map and finite time Lyapunov exponent field and outputs them both as .ppm and .csv files.
