Back in April,
Chris Webb posted an entry on Analysis Services stored procedures asking for volunteers to joining him in creating a few useful examples that people could download. I was one of those volunteers and after several months of work behind the scenes, we are at a point where we are happy to release beta 1 on CodePlex here:
http://www.codeplex.com/Wiki/View.aspx?ProjectName=ASStoredProcedures
Have a read of the CodePlex site - it's reasonably well documented, and you can download the source code as well as the dll.
We hoped to provide some samples that would both be immediately useful and serve as a launching point for people to create their own stored procedures - hopefully you'll find at least one or two useful ones. If you have any feedback, suggestions, bugs to report etc then please do so on Codeplex rather than here.
