In this tutorial we’ll learn how to install Julia on Ubuntu 16.04 (Xenial Xerus).
Julia is a high-level, high-performance dynamic programming language for numerical computing. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy and an extensive mathematical function library.
Several features of Julia
- Multiple dispatch, ability to define function behavior across many combination of argument types
- Dynamic type system
- Good performance, approaching statically-compiled language like C
- Built in package manager
- Can call Python function and C function
- Designed for parallelism and distributed computation
- Ubuntu 16.04 including variant like Kubuntu and Xubuntu.
Install Julia From Ubuntu Repository
Julia is available from Ubuntu 16.04 repository. To install Julia we can run commands below
Update apt database using the command below
$ <span class="token function">sudo</span> <span class="token function">apt-get</span> update
