 Hi,

 I used accumulator's median feature to calculate mean/median of input
 data. I also used armadillo library's mean/median. The mean from two
 libraries always agree. However the medians don't. I tried to give
 1,2,3,4,5 input data to the program. and found accumulator's median
 outputs 0 if the number of input data is 1 or 2. It starts to output non-
 zero median if given more than 2 data points however, first two data
 points are not used.

 Please check what is going on.

 Thanks,
 yu
