assigning values to a matrix

so I have this matrix,and I want everything on the 4th row to become 4s.
a=zeros(10,10)
I tried a(30,40)=4, but that altered the column instead of the rows, and also changed that highlighted position to 4, which I don't want. changing the range doesn't seen to do much to solve that. How can I assign values to the rows instead of the columns?

This:
a(4,:) = 4
produces:
a =
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
4 4 4 4 4 4 4 4 4 4
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
