Can movsum be modified a way, so that it will gain the following output:

A=[1,2,3,4,5,6,7,8,9] B=movsum(A,?) B=[1,3,6,10,15,21,28,36,45] My aim is to build a sum along the vector; adding a value to the previous sum. Thanks for helping.

cumsum()

Note that cumsum is the very first function listed in movsum's "See Also" list, so it is quite easy to find, even starting from just knowing movsum.

Thanks guys, Matlab is quite new to me.
