     5 * 我曾在李開復來台演講中聽過 Google 有人在研究如何用 MapReduce 作矩陣運算的研究,因為在科學應用上矩陣運算是非常重要的數値方法。簡單搜尋了一下,這幾篇看起來不錯:
     6 * [http://homepage.mac.com/j.norstad/matrix-multiply/index.html A MapReduce Algorithm for Matrix Multiplication]
     7  * 有範例原始碼可以下載,不妨參考看看
     8 * [http://mail-archives.apache.org/mod_mbox/hadoop-common-user/201002.mbox/%3C594058.92299.qm@web31915.mail.mud.yahoo.com%3E Re: Inverse of a matrix using Map - Reduce]
     9  * 有人問怎麼算反矩陣,提到可以用 ChainMapper/ChainReducer
     10 * [http://stackoverflow.com/questions/388302/how-to-implement-eigenvalue-calculation-with-mapreduce-hadoop how to implement eigenvalue calculation with MapReduce/Hadoop?]
     11  * 連求特徵値都出現了,有很多參考資料,待消化~
