cumsum (Matlab function) Cumulative sum

## Matlab/Scilab equivalent

Matlab | Scilab
    cumsum
    cumsum

## Particular cases

C=cumsum(A)

  If A is a matrix, cumsum(A) is equivalent to cumsum(A,1) in Matlab whereas in Scilab cumsum(A) gives the cumulative sum of all the entries of A taken columnwise. Actually, Matlab works on the first non-singleton dimension and Scilab does not.

C = cumsum(A,dim)

  Matlab can work with dim greater than number of dimensions of A but Scilab can not, in this can use mtlb_cumsum instead.

## Examples

Matlab | Scilab
    B = cumsum([1,2,3;4,5,6])
    B=[1,2,3;5,7,9]
    B = cumsum([1,2,3;4,5,6],1)
    B=[1,2,3;5,7,9]
    B = cumsum([1,2,3;4,5,6])
    B=[1,7,15;5,12,21]
    B = cumsum([1,2,3;4,5,6],1)
    B=[1,2,3;5,7,9]
