Introduction

In this tutorial we learn how to install armadillo on Fedora 34.

What is `armadillo`

Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. Integer, floating point and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS libraries. A delayed evaluation approach is employed (during compile time) to combine several operations into one and reduce (or eliminate) the need for temporaries. This is accomplished through recursive templates and template meta-programming. This library is useful if C++ has been decided as the language of choice (due to speed and/or integration capabilities), rather than another language like Matlab or Octave. armadillo 10.6.0 2.fc34 x86_64 35 k armadillo-10.6.0-2.fc34.src.rpm updates Fast C++ matrix library with syntax similar to MATLAB and Octave http ASL 2.0 Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use.

We can use yum or dnf to install armadillo on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install armadillo.

Install armadillo on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install armadillo using dnf by running the following command:

sudo dnf -y install armadillo

Install armadillo on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh
