At the present time, dense matrix/vector almost implemented except below list:
- Matrix.Norm - DenseMatrix.multAdd(double alpha, Matrix B, Matrix C) Matrix.Norm.One is that find the maximum absolute row sum of matrix. Here's my mapreduce idea. - A map task receives a row n as a key, and vector of each row as its value - emit (row, the sum of the absolute value of each entries) - Reduce task select the maximum one Does anyone can help me to implement this? And, Any advices are welcome. -- Best Regards, Edward J. Yoon [email protected] http://blog.udanax.org
