矩陣中Col累積和的等價性

所有，
有沒有辦法在矩陣上執行列累積函數？

 

  對於Eg Col累計和（）。Col累計平均值（）等

沒關係。 

 

dt = New Table(); 
dt << New Column("RandomList",Numeric,Continuous,<< Set Values(Random Index(10^3,10^2))); 
dt << New Column("TestColCumSum",Numeric,Continuous,Formula(Col Cumulative Sum(:RandomList)));

mat_1 = dt:RandomList << get Values; 
Res = Cumulative Sum(mat_1); 
dt << New Column("TestColCumSum-1",Numeric,Continuous,<< set Values(Res));
