This website is the promotional and principal online sales channel of Mathematical Services Limited. For the history, rational, particulars and main activities of the Company see the 'About' link in the menu on the left. Currently the main offering is quality numerical linear algebra software, to Households and Companies.

There is also pages devoted to books and booklets that I have written in 3 areas, which can be purchased.

Firstly, 4 books with mathematical results in an emerging area of finite group theory, some of which are original (1st June 2021).

Secondly, 3 books which are modern picture books about Birkenshaw in West Yorkshire, UK, together with social and historical commentary.
STOP PRESS: There is currently a 13-20% price reduction on all languages in this series. 

Thirdly booklets explaining the origin of names.

There is also a page devoted to database applications that I have written.

Here you can find software to perform vector and matrix manipulations, in the Microsoft environment.

All numerical linear algebra functionality is now available in the free version.

In the free version you can plot graphs of vectors and matrices (contour plots), save the graphs in various file formats for reports, and view vectors and matrices in an editor whilst designing a routine or application. You can also perform calculations using the powerful SVD decomposition, matrix Eigenvalue and Eigenvector calculations, non-linear fitting routines, and the Fast Fourier Transforms.
The software is particularly useful for using in traditional lidar developments.

Please see the links on the left hand side.

This Compamy is a multi-lingual international British Company. Part of the offering will be aimed towards applications which can be operated in any language of the world one chooses, wherever one is. In addition part of the offering will permit you to configure a (Microsoft) application in any language one chooses, whilst working in any language one chooses. This is the equipment offered to you (with USA support) at a very resource effective cost.

At the moment the English documents and wording must be regarded as definitive.

There is an issue with the supplier of software and the customer: how does one keep the customer up to date with faults (bug fixes) in the software, yet make it available, at reasonable cost, without it going out of date immediately it is issued. This Company's answer to this is to initially make the software availble on physical media, and support any puchaser of it with needed updates, until sufficient depth and stability in the software is attained that it can be left to electronic provision.

The Company contact details can be found in the 'About' menu on the left.
