Hello,

I'm looking for a way to perform clustering separately on matrix rows and than on its columns, reorder the data in the matrix to reflect the clustering and putting it all together. The clustering problem is easily solvable, so is the dendrogram creation (for example in this blog or in "Programming collective intelligence"). However, how to reorder the data remains unclear for me.

Eventually, I'm looking for a way of creating graphs similar to the one below using naive Python (with any "standard" library such as numpy, matplotlib etc, but without using R or other external tools).

MySQL's unique architecture allows for plugin storage engines. There is the MyISAM storage engine, the ARCHIVE storage engine and the InnoDB storage engine; so it makes sense then that MySQL's clustering solution involves a storage engine as well, namely the NDB (Network DataBase) storage engine. >>> More
