How to install Julia on Ubuntu Linux?

Julia is a high-level, general-purpose, dynamically typed programming language that can be used for developing any kind of application. It provides functions for matrix manipulation, data visualization, etc so it is best suited for numerical analysis and scientific computing.

Julia is capable of direct calling C and Fortran libraries. You can create scripts in interactive mode (REPL) and by using its embedding API you can use Julia with other programming languages easily.

In this article, I will discuss how to install Julia on Ubuntu Linux.

Features of Julia

  • Free and opensource
  • It is simple and fast
  • Dynamically typed which feels like a scripting language
  • Provides various functions for matrix manipulation and data visualization
  • It can use C and Fortran libraries directly
  • Can be easily embedded into other languages
