Please read the next sections if you download software I wrote in Matlab.
Some of my software is written in Matlab, a very powerfull programming environment for scientific software (www.mathworks.com). Normally, Matlab runs as an interpreter for the source code files. If I want to distribute my software, then there are 2 options:

1. I provide the source files I have written. This means that you must have a version of Matlab installed with licences for the Toolboxes that are used by my source files. The advantage is that the source files are, within certain limits, backwards compatible with older versions of Matlab.
2. Matlab can also generate a small set of files for my application, resulting in a (sort of...) stand-alone application which can run without the need for a full Matlab installation. The user should however not only obtain the stand-alone application, but he must also install the so called MCR (Matlab Component Runtime) libraries. This MCR embeds the Matlab interpreter and all available functions in all Toolboxes. If you have multiple stand-alone applications that you want to run on your computer, you only have to install the MCR once.

The second option seems to be the best, but there are two 'small' drawbacks. First of all, different versions of the MCR are usually completely incompatible. This means that I have to use a certain MCR version as long a possible in order to have as much as possible applications compatible with the same MCR. Why this is important? Well, that's the second drawback: the current version of the MCR is almost 150 Mbytes large! You just don't want to install many different MCR versions.
If you don't have a Matlab version at home that supports my source files, you'll have to obtain the MCR for which the stand-alone executables were generated. My website runs under a small account with a fair data limit, and if only a few interested visitors of my website download the MCR then I exceed that data limit very quickly. Therefore, I do not make the MCR available here on my website. So, send me an email and I'll see if I can upload the stuff to some free virtual disk account on the Internet instead.
This is simple, just start by installing the MCR and follow the guidelines of the automatic installer. You must have administrator rights on your computer in order to correctly install the MCR. After that, copy my Matlab software to a folder of your choice. Just double-click the executable and you're good to go!
If you downloaded a new version of my software, then simply replace the old files by the newly downloaded files. In the folder where you copied the files, you may notice one or more folders which where created by the Matlab software. The name of these folders end with '_mcr'. Make sure that you delete these folders!
