How To Install levmar on Fedora 34

levmar is Levenberg-Marquardt nonlinear least squares algorithm Levenberg-Marquardt nonlinear least squares algorithm

Introduction

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

What is `levmar`

levmar is a native ANSI C implementation of the Levenberg-Marquardt optimization algorithm. Both unconstrained and constrained (under linear equations, inequality and box constraints) Levenberg-Marquardt variants are included. The LM algorithm is an iterative technique that finds a local minimum of a function that is expressed as the sum of squares of nonlinear functions. It has become a standard technique for nonlinear least-squares problems and can be thought of as a combination of steepest descent and the Gauss-Newton method. When the current solution is far from the correct on, the algorithm behaves like a steepest descent method to converge. When the current solution is close to the correct solution, it becomes a Gauss-Newton method. levmar 2.6 7.fc34 x86_64 60 k levmar-2.6-7.fc34.src.rpm fedora Levenberg-Marquardt nonlinear least squares algorithm http GPLv2+ levmar is a native ANSI C implementation of the Levenberg-Marquardt optimization algorithm.

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

Install levmar 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 levmar using dnf by running the following command:

sudo dnf -y install levmar

Install levmar on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum 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 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 levmar using yum by running the following command:

sudo yum -y install levmar

How To Uninstall levmar on Fedora 34

To uninstall only the levmar package we can use the following command:

sudo dnf remove levmar
