Installation

To install the package, simply run

python -m pip install git+https://github.com/changhoonhahn/pySpectrum.git

There's some complications with using FFTW3 installs. I've listed some examples on different HPCs in install examples.

required packages:

• numpy
• scipy
• astropy
• matplotlib
• f2py

Also requires FFTW3. On macs, you can install FFTW3 using homebrew.

Coming Soon
