How To Install levmar on CentOS 7
Introduction
In this tutorial we learn how to install levmar on CentOS 7.
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 the current solution is close to the correct solution, it becomes a Gauss-Newton method.
We can use yum or dnf to install levmar on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install levmar.
Install levmar on CentOS 7 Using yum
Update yum database with yum using the following command.

Install levmar on CentOS 7 Using dnf
If you don’t have dnf installed you can install DNF on CentOS 7 first.
