Re: Sum Row In Matrix

[Ian McCallion]

Very weird code for what is effectively a cumulative sum of the rows:

dailyprofit = [1,2,3;4,5,6];

A=dailyprofit;

for i=1:columns(dailyprofit)

for ii=1:rows(dailyprofit)

 if i>1
     A(ii,i)=A(ii,i-1)+dailyprofit(ii,i);
   endif  

endfor  

endfor

A

B=cumsum(dailyprofit,2)

Cheers... Ian
