matlab r2011b license file 19

Matlab r2011b is one of the previous releases of matlab that was launched in September 2011. It introduced some new features and enhancements, such as faster startup on Windows, spreadsheet import tool, gridded interpolant object, mixed integer nonlinear programming in genetic algorithm solver, project manager for library and model component configuration, concurrent execution on multicore processors for host-based targets, enhanced OOP, enumeration, and more.

A license file is a specially formatted text file that contains encrypted product passcodes for each product that you are licensed to install and run. It also specifies the number of keys available for each product, the expiration date of the license, and other information. You need a license file to activate and use matlab r2011b on your computer or network.

How to obtain a license file for matlab r2011b

To obtain a license file for matlab r2011b, you need to follow these steps:

• Obtain a software license or trial from MathWorks. You can purchase a license from the MathWorks Store or contact your administrator if you are using a network or campus-wide license. You can also request a free trial from the MathWorks website.

• Download the installer from MathWorks Downloads. You need to sign in to your MathWorks Account and select the release that matches your license. You can choose between online or offline installation options.

• Run the installer and enter the activation key and file installation key. The activation key is a 25-character code that links your MathWorks Account to your license. The file installation key is a 16-digit code that enables you to install matlab products without using an internet connection. You can find these keys in your MathWorks Account under My Products and Services.

How to update or modify a license file for matlab r2011b

In general, you do not need to modify the license file on the server or on the client computers. However, in some situations, you may need to edit the license file, such as:

• When you change the license server name (for example, if the license is now being hosted on a new server).

• When you add or remove products from your license (for example, if you purchase a new product or discontinue using an existing product).

• When you renew or extend your license (for example, if your license is about to expire or has expired).

To update or modify the license file for matlab r2011b, you need to follow these steps:

• Access the license file on the server or on the client computers. The location of the license file depends on the type of installation and operating system. For example, on Windows, the default location for a network license file is C:\Program Files\MATLAB\R2011b\licenses\network.lic. You can also use the license command in matlab to display the path to the license file.

• Edit the license file using a text editor. You need to make sure that the syntax and format of the license file are correct and consistent. You can refer to the license file reference for more details on how to edit the license file.

• Restart the network license manager after editing the license file. You need to stop and start the network license manager service on the server to apply the changes to the license file. You can use the lmtools utility on Windows or the lmutil command on Linux or Mac to restart the network license manager.

How to troubleshoot common license file issues for matlab r2011b

Sometimes, you may encounter some license file issues that prevent you from using matlab r2011b properly. These issues may be caused by various factors, such as network problems, configuration errors, or corrupted files. To troubleshoot common license file issues for matlab r2011b, you need to follow these steps:

• Check the license status and diagnose license errors. You can use the license command in matlab to display information about your current license status, such as expiration date, number of keys available, and error messages. You can also use the lmstat command on the server or client computers to check the status of the network license manager and the licenses in use.

• Resolve common license errors such as invalid host ID, invalid passcode, or license checkout failed. These errors may indicate that your license file is incorrect, outdated, or incompatible with your installation. To resolve these errors, you need to verify that your license file matches your activation key and file installation key, that your host ID matches your computer's MAC address, that your passcode matches your product code, and that your firewall or antivirus software is not blocking the communication between matlab and the network license manager.

• Contact MathWorks support for further assistance. If you cannot resolve the license file issues by yourself, you can contact MathWorks support for help. You can submit a service request online or call them at 508-647-7000 (U.S.) or +44 (0) 1223 423200 (U.K.). You may need to provide some information such as your MathWorks Account number, your activation key, your error message, and your diagnostic report.
