RE: Cumulant vector

[Bhaskar Mehta]

a=[1 2 3 4 5] ;b=zeros(size(a));
b(1,1)=a(1,1);
for i=2:size(b,1)
b(i,1)=a(i,1)+b(i-1,1);
endfor

do it c++ (.oct file) and it should be blazingly fast.

Subject: Cumulant vector

Hi all,
 
There is some function or easy way in Octave that permit you acumulate
reference points?
 
I mena, for example,
 
a=[1 2 3 4 5] 
 
b=[1 3 6 10 15]
 
b sums the previous sum of the matrix. 
 
so that b is the results of doing these kind of operations:
 
 
b[1,1)=a(1,1) 
 
b(1.2)=b(1.1)+a(1.2)....b(1.5)=b(1.4)+b(1.5)
 
Thanks in advance.
