multi dimension colon operation

I don't know if 'multi dimension colon operation' can explain my question, what I hope to do is given a matrix:

matrix_in = [1, 2, 3;
             2, 3, 4;
             3, 4, 5];

for each of the i=1:3 line, return the sum of matrix_in from line 1 to line i, so the output is:

matrix_out = [1, 2, 3;
              3, 5, 7;
              6, 9, 12];

is there a way of doing this with one line code? Thanks!
