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]
