dear everyone :
this is my problem,firstly,i create two matrix files a and  b,
a = 1 3 2      b = 3 2
       2 3 1            1 5
       1 4 5            2 1
then i put them to filesystem. 
i use mahout command :mahout seqdirectory change a and b to seq file a1 and b1.
then,use mahout command :mahout matrixmult , a1*b1
it works,but the anser is
