+% NANSUM same as SUM but ignores NaN's. 
+% NANSUM is OBSOLETE; use SUMSKIPNAN instead. NANSUM is included 
+%    to fix a bug in some other versions.

+% Y = nansum(x [,DIM])
+% 
+% DIM	dimension
+%	1 sum of columns
+%	2 sum of rows
+%	default or []: first DIMENSION with more than 1 element
+% Y	resulting sum
