Am I correct in thinking that the second parameter of build() must be an expression that evaluates to a numeric value? If this is the case, is there a way to extract a single numeric value from a 1x1 numeric array?
Suppose, for example, I’d like to use an AFL expression as the expression parameter of build(), an AFL expression that evaluates to a 1x1 singleton array. SciDB throws an error when I try to run the query, stating that it expects a number as the parameter, not an array.
Any suggestions appreciated, thanks, Patrick
