This function accepts a single input source containing either univariate matrix instances or multivariate matrix instances. The input source can have an associated payload content type of REAL (univariate matrix) or MULTIVAR_REAL (multivariate matrix).
The maximum supported number of entries (size) for the multivariate matrix input is less than the maximum supported size for the multivariate matrix. A SQL error is returned if the size limits are exceeded. A multivariate matrix that exceeds the size limitations can be re-entered as a collection of individual single-field queries.
