calculating row sum except one cell.

[ha lee]

HI statalist.

I'm trying to calculate summation value of each row without one cell.

I do not know how to express it.

For example,

if A=(1..3\4..6\7..9)

I would like to calculate summation of first row except A[1,1], then I got the value of 5.(2+3)

And then I might wanna know the summation value of the third row except A[3,2], the value will be 7+9=16... and so on.

Could anyone help me to calculate it??
