matrix manipulation

Dear MonetDB users!

I would like to do some simple calculations (matrix multiplication and inversion) with large matrices (cca 40k by 40k or more). We are using PostgreSQL & R but we are facing problems when matrix doesn't fit memory.

My initial idea was to use SciQL, but probably it is not merged into MonetDB yet [1]?

I am sending also short presentation [2] illustrating nature of our data and calculation (slide 6).

Thank you for your suggestions! Jiří.
