The NAG Toolbox for MATLAB^®

Users of MATLAB gain advanced numerical capabilities from NAG

The NAG Toolbox for MATLAB makes the extensive mathematical and statistical functionality of the highly regarded NAG Library available to users of MATLAB.

When using the NAG Toolbox for MATLAB users gain access to over 1,300 NAG Library algorithms, all which have been through NAG’s stringent testing procedures, giving extensive numerical functionality not otherwise available, or only by buying several specialist toolboxes.

Why should I use the NAG Toolbox for MATLAB?

By using the NAG Toolbox for MATLAB, you will gain from the following benefits:

• Increased productivity - NAG routines have been written by experts and are globally renowned for their accuracy, flexibility and robustness
• ALL NAG routines are accompanied by expert and unique documentation making the selection of the right algorithm quick and easy
• Also included in the documentation for each NAG Library routine is example MATLAB code showing how to call the routine
• Numerical code is easier to read and maintain as many routine arguments become optional or unnecessary

“I am impressed by the optimization algorithm provided by the NAG Toolbox for MATLAB. It improves the results for my maximum likelihood estimations for situations where the sample size is small causing non-concentrating likelihood and when the likelihood functions have 'ridges'. Ordinary algorithms, for example Newton * gradient search, perform poorly in these situations.”
