Sum of positive values function. SUMPOS(range) calculates the sum of the positive values in range.
The argument range can be a list of numbers, cell addresses, cell ranges (such as A1:A10).
Range can also be a matrix. In that case the function returns a matrix with one row and the same number of columns, with each element the SUMPOS of the corresponding column. If range is a row matrix, it is converted to a column matrix first.
