NAG Toolbox for MATLAB®

MBMI622DDL - License Managed

Mac OS X 10.5 (Intel 64 bit), MATLAB R2009b - R2010b

Installer's Note


1. Introduction

This Installer's Note is essential reading for whoever is responsible for the installation of this implementation of the NAG Toolbox for MATLAB. Please note administrative (root) rights are required in order to install the NAG Toolbox for MATLAB.

Your attention is drawn to the terms and conditions of the Software License Agreement regarding the use of NAG software. Any request to use this software other than on the licensed computer must be referred to NAG, as should requests for information about the availability of other implementations.

2. Implementation Provided

2.1. Applicability

This implementation is a compiled, tested, ready-to-use version of the NAG Toolbox for MATLAB that is considered suitable for use on the computer systems detailed below:

hardware:             Apple Intel Mac 64-bit
operating system:     OS X 10.5 and compatible
MATLAB Version:       7.9 (R2009b), 7.10 (R2010a) and 7.11 (R2010b)

The system must have MATLAB installed. This implementation may work with later versions of MATLAB. More details may be available on the post release page (see Section 2.2).

Where the information in this document refers to "compatible MATLAB versions", this means MATLAB R2009b - R2010b. Even if this toolbox is compatible with later versions of MATLAB, the installation procedure will not automatically update the MATLAB path and MATLAB script for versions of MATLAB newer than R2010b; they will need to be modified by hand as described below.

2.2. Post Release Information

Please check the following URL:

for details of any new information related to the applicability or usage of this implementation.

3. Distribution Medium

The software is available to download from any of the NAG Web sites (see NAG Websites). Upon request, the software may be distributed by CD.

3.1. File Sizes

The approximate files sizes are given below
Help material    40 MB
Toolbox files    145 MB

4. Installation

If you have downloaded the toolbox materials from our website, double click on MBMI622DDL.dmg. This will extract the package mbmi622ddl.pkg in addition to the files in.html and License

If you received the product on CD then simply insert it in your CD drive and, if necessary, mount the CD device (normally this will happen automatically). This will contain the same files as the .dmg file above.

To install the NAG Toolbox for MATLAB software, double click on mbmi622ddl.pkg and follow the instructions.

The toolbox software will be installed in /opt/NAG/mbmi622ddl. By default, your MATLAB path and MATLAB script will be updated during installation for compatible MATLAB versions if they were installed in the default location (i.e. under /Applications) in your system otherwise, as described in Section 4.1, you will have to edit them manually.

After installation, you should ensure that the software described in Section 4.1 is present and accessible. Then on starting the MATLAB Help browser you should see the entry NAG (64 bit) Toolbox in the Contents list.

A quick test that the software has been correctly installed is to type a00aa at the MATLAB prompt, which should print some implementation details.

4.1. Installation Options

The NAG Toolbox MBMI622DDL is installed under /opt/NAG/mbmi622ddl. The help files will be placed in the directory /opt/NAG/mbmi622ddl/help/toolbox/NAG while the executable files will be placed in /opt/NAG/mbmi622ddl/toolbox/NAG/mex.maci64.

The MATLAB path is updated during installation for existing compatible MATLAB versions, i.e. the file toolbox/local/pathdef.m will be modified for each compatible MATLAB version in your system. Then this file will have the lines:

     '/opt/NAG/mbmi622ddl/toolbox/NAG/mex.maci64:' ...
     '/opt/NAG/mbmi622ddl/help/toolbox/NAG:' ...
     '/opt/NAG/mbmi622ddl/help/toolbox/NAGToolboxDemos:' ...
inserted. If you install a newer compatible version of MATLAB after installing the NAG Toolbox for MATLAB you may choose to reinstall the NAG Toolbox. This will update the MATLAB path in the new version of MATLAB without further modifying the MATLAB path in the previous version(s). If you choose not to have your path modified then there are a number of ways by which this may be done by hand. Search for "matlab path" in the MATLAB online help system for one method, and for pointers to several others. If updating by hand then it is essential to ensure that the directory containing the help files appears after that containing the executable files. For example, your MATLAB path should contain the directories: in that order.

Your MATLAB script will be modified during installation for all existing compatible versions in your system (if necessary) and the file bin/matlab in the MATLAB distribution will have the lines:

  # Inserted during installation of NAG Toolbox for 64 bit OS X
added to it. If you decide to modify your DYLD_LIBRARY_PATH by hand for a new installation of MATLAB then a good approach is to edit the definition of LDPATH_PREFIX in the file. The main reason that this is not the approach taken by the installation script is that MATLAB allows a user to override the system-wide version with their own version(s) and so it is not possible reliably to install the toolbox for all users this way. The MATLAB documentation contains more information about the use of the file.

4.2. Uninstalling the Software

The NAG Toolbox for MATLAB and its related materials are installed under /opt/NAG/mbmi622ddl and the folders are

You may run the script UNINSTALL.maci64 which is created during installation and can be found in the directory /opt/NAG/mbmi622ddl, using the commands

 cd /opt/NAG
This will remove the NAG toolbox and will restore your MATLAB path and MATLAB script for all compatible MATLAB versions.

Alternatively, you may either drag the directories shown above to the trash or from the Finder menu choose "Move to Trash" and then select "Empty Trash" from the Finder menu. Using this method, you will need to modify your MATLAB path and MATLAB script to remove references to the NAG Toolbox yourself.

4.3. License Management

The use of the NAG Toolbox is controlled by the Kusari license management system. This release of the NAG Toolbox uses version 2.2-20 of Kusari.

A short term (demonstration or trial) license key contains one or more lines like the following:

MBMI622DD TRIAL 2010/10/10 "EMnxidA3oeoj0F1Yvi5ibxPjB7"
Specifically, it has a line containing the word TRIAL. Longer term license keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These license keys include the word NODE instead of the word TRIAL above.

In order to enable the software, NAG will issue you with a license key. The license key is a simple text file containing details of the software that will be enabled.

License key request and installation is performed through the Apple Installer when mbmi622ddl.pkg is installed. During installation, you will be prompted for a license key. If you do not have a license key, a request form will be generated for you to complete and send to NAG via fax or e-mail.

Once you have obtained one of the above license keys you can enter it into the license installer (License By default, the license installer will save the license key in /opt/NAG/nag.key (prepending to the file if it already exists). The toolbox will then validate the license at runtime.

If you need to update or change the license key after installation, we recommend that you run the license installer again.

Further details about Kusari and how it may be configured to suit your local circumstances (e.g. how to install the license key on a server) are included in the Kusari License Management documentation in the license/doc/ subdirectory of the software distribution. See also the Kusari FAQ:
