Libpolycomp user's manual

This is the documentation for the Libpolycomp library (https://github.com/ziotom78/libpolycomp), a C library for compressing one-dimensional numerical data series.

Libpolycomp has been written on a Linux 64-bit system, but it should be fairly straightforward to port it to other operating systems/architectures, as it is written using a portable sub-set of C89.

The API has been designed with the purpose of easing its call from other languages; a Python interface and a stand-alone program are available at the site https://github.com/ziotom78/polycomp .

The library offers the following compression schemes:

• Run-Length Encoding
• Differenced Run-Length Encoding
• Floating-point quantization
• Polynomial compression functions

The library implements also a number of ancillary functions to compute least-squares polynomial fits (Least-squares polynomial fits) and discrete Chebyshev transforms (Discrete Chebyshev transforms).
