Theoretical derivation indicates that time averaged three-order cumulant of signals, which are from(random) phase harmonic processes, is nonzero and its one-dimension slice is also a harmonic process.
理论推导表明，随机相位谐波过程时间平均三阶累积量为非零值，而且其一维切片仍然是谐波过程。
A somewhat more radical idea is to slice up multidimensional arrays into parallel single one-dimension arrays.
一个激进的方式是，切片多维数据为平行的一维数组。
