# What’s it for
fds is a research tool for computational simulations that exhibis chaotic dynamics. It computes sensitivity derivatives of time averaged quantities, a.k.a. statistics, with respect simulation parameters.
For an introduction of chaotic dynamics, I highly recommend [Strogatz’s excellent book](https://www.amazon.com/gp/product/0813349109). For a statistical view of chaotic dynamical systems, please refer to [Berlinger’s article](http://www.uvm.edu/~pdodds/files/papers/others/1992/berliner1992a.pdf). Algorithm used in this software is described in [the upcoming AIAA paper](https://dl.dropbox.com/s/2e9jxjmwh375i01/fds.pdf)
# Download and use
The best way to download fds is using pip. Pip is likely included in your Python installation. If not, see [instruction here](https://pip.pypa.io/en/stable/installing/). To install fds using pip, simply type
` sudo pip install fds `
