test for uci data set-- Localization Data for Person Activity Data Set, calculate the features vector [x[n], y[n], z[n], SMV[n], SMA[n]].
The features vector are SMV, SMA, the angle of acceleration.
SMA is defined as SMA[n] = 1/N( x[n]+x[n-1]+...+x[n-N+1] + y[n]+y[n-1]+...+y[n-N+1] + z[n]+z[n-1]+...+z[n-N+1])
N is the last data record nums.
