Dependencies
============
Other versions may work but this hasn't been tested
- libpng (1.6.37)
- mpc (version 1.2.1)
- mpfr (version 4.1.0)
Using the [GNU Guix] package manager, you can simple run
,----
| guix shell -f guix.scm
`----
to get a shell with everything set up. You can also authenticate the
git history with
,----
| guix git authenticate -k origin/keyring \
| 1fb8ce84b2e4329007a23c047a8ea211d629da00 \
| 'D5BA 4708 FA7D 0AFD 9C0E 6556 ECD7 F82F 5327 404C'
`----
In order to get a (hopefully) identically environment, you can run
,----
| guix time-machine --commit=716f2b330fb0566e48423a7f928759a351e73850 -- \
| shell -f guix.scm

Usage
=====
The coefficient file has to be a whitespace seperated list of
coefficients. They can be written as decimal numbers (e.g. `23.3'),
floating point numbers (e.g. `1.25e+7') or pairs of two such numbers
as real and imaginary part respectivel (e.g. `(3 1.3e-3)'). As an
example, the following plots the geometric series up to \(O (z^{11))\)
on a disk of radius \(1.2\) around \(0\) with a resolution of 400 by
400 pixels.
,----
| cat >coeffs.txt <<EOF
| 1 1 1 1 1 1 1 1 1 1 1
| EOF
|
| polyplot -R400 -r1.2 coeffs.txt
