Load load the matrix from the matrix file using user specified !MapReduce class.
for example:
hama> a = load "fileA" as Matrix using !MyMapReduce.class MAP 10 REDUCE 1;
hama> b = load "fileB" as Matrix using !MyMapReduce.class;
Add the matrix addition.
such as :
hama> c = a + b.
Multiply the matrix multiplication.
such as :
hama> d = a * b.
Save save the matrix as a file.
such as :
hama> save c as "fileC".
