# Welcome to catch22 Want to do feature-based time-series analysis, fast, and in a coding language of your choice? The ***catch22*** feature set provides open access to a powerful reduced set of time-series analysis features that compute quickly. * A **generally applicable** subset of 22 features from the [*hctsa*](https://github.com/benfulcher/hctsa/tree/c50568f53133ba7cdc77b5ed2bedb36bbe93ef28) time-series feature library that provide an **effective** general summary of time-series statistical properties. * Available as native [**Python**](https://time-series-features.gitbook.io/catch22/language-specific-docs/python), [**Julia**](https://time-series-features.gitbook.io/catch22/language-specific-docs/julia)**,** [**MATLAB**](https://time-series-features.gitbook.io/catch22/language-specific-docs/matlab)**,** and [**R**](https://time-series-features.gitbook.io/catch22/language-specific-docs/r) packages (that call[ **C-compiled**](https://time-series-features.gitbook.io/catch22/language-specific-docs/c-compiled) executables). ## Language-Specific Documentation Choose your coding language below (or from the sidebar). Each pages cover **all** aspects of usage in a particular language including **installation guides**, **tutorials** and **frequently asked questions**.
