Numbers in row 1 are: 103, 61, 0, 0, 62, -999, -999, 0, 0, 2
I'm using sum(B,2)
but how can I sum all rows greater than or equal to 0

Explain what it means to "sum all rows greater than or equal to 0"
and what that has to do with numbers greater than -1
and what that has to do with the values in row 1.

B = [103, 61, 0, 0, 62, -999, -999, 0, 0, 2]
sum( max(B, 0), 2)

Note that sum(B(B>0)) would only work for a single row, whereas the max solution works for multiple rows
