Subject MatrixMultiplicationJob Input query
Date Mon, 14 Jan 2013 06:50:56 GMT
I want to execute MatrixMultiplicationJob provided in Mahout. I understand that the input
file should be in SequenceFileFormat with input Key as IntWritable and Value as TupleWritable.

If my matrix is  2x3 like :

A =  1 2 3
        4 5 6

What should I keep as key and value in SequenceFileFormat so that I can provide it in MatrixMultiplicationJob
as input. Sorry for the basic question but Im new to Mahout and not finding much details of
MatrixMultiplicationJob execution.
