The complete NAG Library Manual, Mark 22 can be viewed online in the following formats:
- XHTML+MathML, a fully linked version of the manual using XHTML and MathML (recommended for browsing) and providing links to the PDF version
of each document (recommended for printing); and
- PDF, a full PDF manual browsed using the PDF bookmarks, or via HTML index files.
This note tells you how to obtain the software required to view the documentation and advises you on how best to navigate
the files with or without an HTML browser.
2 XHTML+MathML Format
2.1 Viewing XHTML+MathML Files
These files do not use any proprietary browser specific features, and conform to relevant W3C Recommendations (Standards)
(XHTML 1.0, MathML 2.0, CSS 2.1, XSL 1.0).
Support for these languages may require updating your browser and/or installing a (free) third party extension. Details of
system requirements for various platforms are detailed below. This document is restricted to providing information for the
more widely used browsers. If you require information for additional browers please contact NAG
2.1.1 Internet Explorer
Internet Explorer version 6.0 or later is required. The latest version of Internet Explorer is always available from:
If you have Internet Explorer 6.0 (but not 5.5) the mathematics will be displayed to some extent without any additional plug-in,
but to produce high quality mathematics rendering you should obtain the free MathPlayer from Design Science.
2.1.2 Firefox (and other Mozilla based browsers)
All versions of Firefox should display XHTML+MathML files by default. MathML support is part of the core rerendering engine
in this browser.
You may need to install additional fonts (if so, a dialog box will alert you when you first view a page containing mathematics).
For Firefox 3, you need the STIX beta fonts, and for earlier versions you need the TeX fonts. Full details of the installers
available for these fonts on all the major platforms are included in the Firefox MathML fonts page:
2.1.3 Opera and Safari
Opera and Safari do not have native MathML support however they do have very modern and compliant CSS engines which allow
most of the MathML to be rendered legibly but without the finer typographical refinements. The stylesheet used with the documentation
will detect these browsers and automatically apply a suitable CSS styling.
2.2 Navigating XHTML+MathML Files
A main index file has been provided (xhtml/FRONTMATTER/manconts.xml) which links to individual Chapter Contents documents,
which in turn link to a complete set of XHTML files. Use your HTML browser to navigate from this main index file. For each
routine document in XHTML format you are provided with a link to its equivalent PDF file, this file has been provided primarily
for printing purposes.
Each library document contains a number of hyperlinks to particular elements, e.g., argument, sections, chapter contents,
etc.. The following key identifies the colour used for each element:
2.3 Printing XHTML+MathML Files
It is possible to print your XHTML+MathML files from the browser, however support for printing from browsers, especially support
for printing mathematics varies considerably betwen versions of browsers and platforms and printer drivers being used. You
are recommended to use the PDF version of the document for printing and links are provided at the top and bottom of the XHTML
3 PDF Format
3.1 Viewing and Printing PDF Files
If you do not already have a copy of Adobe Acrobat Reader for your platform, a free copy can be downloaded from http://www.adobe.com. Please check this site for availability of a reader for your platform. While we recommend the use of Acrobat, there are
alternative PDF viewers available which can also be used, such as xpdf or ghostview.
If Adobe Acrobat is not running as a plug-in then the bookmark links will not work correctly if you are browsing the PDF files
via http rather than the local filesystem. You are advised to reinstall Adobe Acrobat which should rectify the problem.
Please note that if you are using Adobe Acrobat 4.0 or earlier you might experience some problems when printing documents
that contain non-standard characters, such as integral signs, square roots and large brackets. For instance,
the summation symbol on page 1 of D02TGF
the round brackets on page 2 of F07AWF (ZGETRI)
will appear incomplete when printed using 4.0, but will print correctly using 5.0 or later versions.
We recommend that you use the PDF format when printing library documentation.
3.2 Navigating The PDF Files
The manual is supplied as a set of individual PDF files, one for each routine document, chapter introduction, etc. Each PDF
file contains bookmarks that can be used in Acrobat to navigate between the files. Alternatively, and often more conveniently,
HTML tables of contents are supplied which allow you to navigate to the desired file using an HTML browser, and then use Acrobat
as a browser plugin to read or print the document.
