Installation

Either clone the repository and install locally (best for developer installs):

$ git clone https://github.com/steven-murray/hankel.git
$ cd hankel/
$ pip install -U .

Or install from PyPI:

$ pip install hankel

Or install with conda:

$ conda install -c conda-forge hankel

The only dependencies are numpy, scipy and mpmath. These will be installed automatically if they are not already installed.

Dependencies required purely for development (testing and linting etc.) can be installed via the optional extra pip install hankel[dev]. If using conda, they can still be installed via pip: pip install -r requirements_dev.txt.

For instructions on testing hankel or any other development- or contribution-related issues, see the contributing guide.
