# 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]```
