How to maintain a sum in a matrix with the movsum function

Novice user here. I would like to add each row within a matrix together. Basically, I want to add the second element to the first element, add the third element to that resulting sum, etc. (for a one-column matrix).

For example: A = [1 2 3] Desired result: B = [1 3 6]

I have tried using the movsum function, but I can't seem to maintain the sums within the matrix. It adds together the initial values within the column rather than carrying the resulting sum for each row throughout the matrix.

Is movsum the wrong function?

Any help is greatly appreciated!
