Returns the sum of all the elements in the vector v.
Operands:
X is any expression containing
vector subscripts.
i is a range
of integers. The acceptable range depends on the size of X and the ORIGIN of
the worksheet.
v is a vector.
Notes:
Define the range
variable, i, before using the sum with range
variable operator. To include the range variable as part of the operator,
use the sum without range
variables operator.
If the summand has several terms, be sure to enclose
them in parentheses to keep them inside the summation operator.
Under symbolic evaluation, if no range is specified,
results are typically based on ranges which start at 0 or 1.
