maps an SA with global indices from the rank's support to global indices from the rank's range. The image of each index is a separate SA. See <A HREF="../DM/SAMappingMap.html#SAMappingMap">SAMappingMap</A>, if concatenated output is desired. Since SAMapping is in general multivalued, some global indices are mapped to multiple global indices. Only the indices of the selected type (I or J) are mapped; the other indices and weights, if any, are preserved on the images.
