-## Register MATLAB as a Jenkins Tool
+## Register MATLAB as Jenkins Tool
 To run MATLAB code and Simulink models as part of your automated pipeline of tasks, Jenkins invokes MATLAB as an external program. When you configure your project, you can explicitly specify the MATLAB version that Jenkins should invoke by providing the path to the desired MATLAB root folder. For example, you can use an `environment` block in your `Jenkinsfile` to specify a MATLAB root folder for your Pipeline project.
 
 Instead of specifying the path to the MATLAB root folder on a per project basis, you can register MATLAB as a Jenkins tool, which can then be accessed by any project you configure in Jenkins. To register your desired MATLAB version as a tool, you are required to specify its name and location on the build agent. Once you have registered MATLAB as a tool, you no longer need to specify its root folder path within a project. Jenkins only needs the tool name to access MATLAB.

 1) In your Jenkins interface, select **Manage Jenkins > Global Tool Configuration**. A new page opens where you can register different tools with Jenkins.

-If you define your Pipeline using Scripted Pipeline syntax, you need to prepend the path to the `bin` folder of the desired MATLAB version to the PATH environment variable. Use the `tool` keyword following by the name of the tool to retrieve the path to the MATLAB root folder.
