Information about the package, levmar, which is shipped with common Linux distributions. The levmar package is designed for, Levenberg-Marquardt nonlinear least squares algorithm.
Package Name:
levmar
Summary:
Levenberg-Marquardt nonlinear least squares algorithm
Description:
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: slow, but guaranteed to converge. When the current solution is close to the correct solution, it becomes a Gauss-Newton method.

Control the levmar package with the following handy commands outlined below.
yum install levmar
This command will install levmar on the server.
yum remove levmar
This command will un-install levmar on the server. When you run this command, you will be asked if you are sure that you want to remove levmar, so you have to manually confirm that you want to do this.
yum -y remove levmar
This command will un-install levmar on the server. When you run this command with th e -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove levmar when using the -y flag.
yum update levmar
This command will update levmar to the latest version. When you run this command, you will be asked if you are sure that you want to remove levmar, so you have to manually confirm that you want to do this.
yum -y update levmar
This command will update levmar to the latest version. When you run this command with the -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove levmar when using the -y flag.
yum info levmar
This command will show you core information about the levmar package.
yum deplist levmar
This command will show you the dependencies for levmar. Thankfully, when using Yum, if dependencies are required, these are also installed at the same time so you don't have to worry too much about that.
yum check-update levmar
This command will check if there is an update waiting on levmar. When you run this command this will return nothing if there is nothing to update, or, will return the package name if the package is due to be updated.
