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.


Not sure what you mean by "accumulate reference points" ... but is this the sort of thing you're looking for?

b = cumsum ([ 0, a ]);

or

b = [ a(1), cumsum (a) ];
