How can i operate on every row of a matrix without using any loop?

I have to find the cumulative sum of every row seperately without using any kind of loops in the following matrix;

c = exprnd(1,1000,100);

so i should get a thound rows of cumsum(exprnd(1,1,100)).

Something like this:

A=randi(9,4)
B=cumsum(A,2)

gives:

A =
     8     6     9     9
     9     1     9     5
     2     3     2     8
     9     5     9     2
B =
     8    14    23    32
     9    10    19    24
     2     5     7    15
     9    14    23    25

thank you so much.

what is the function of that 2, i didnt get it?

That specifies the dimension to operate along. i.e. dim2, rows
