Dear Fang There are considerable tutorials available for doing matrix operations.
For example just a quick google search for hadoop matrix multiplications has given this result. http://www.norstad.org/matrix-multiply/index.html Is there any specific matrix operation you are looking for ? If you want to avoid writing java code then high level tools like Pig <http://pig.apache.org/>have already stats functions built in. They internally write java code for you.
