<Syntax> 



SUM ( ARRAY, DIM [ , MASK ] )
SUM ( ARRAY [ , MASK ] )
ARRAY : rank N array of type Integer, Real or Complex;
DIM : scalar Integer in the range 1 to N;
MASK : array of type Logical with the same shape as ARRAY;
Result: Same type and kind as ARRAY. 





<Semantics> 



The result is ARRAY reduced by addition ( + ).
If DIM is absent, this is a scalar equal to the sum of all the masked elements of ARRAY.
If DIM is present, the result has rank N1 and the shape of ARRAY with dimension DIM removed;
each element of the result is the sum of the masked elements in that dimension.
If no elements contribute to a result value, that value is zero.
