" - A is an array with one string attribute\n\n"
"cu(A) returns a sparse array with schema identical to A whose entries contain\n"
"unique elements within each chunk by marking repeated entries empty. The array\n"
"A may be multi-dimensional and chunked arbitrarily. The cu filter is applied\n"
"independently within each chunk. It is intended to help speed up the SciDB uniq\n"
