push_dotproduct
Declaration:
void
push_dotproduct
(EStackIndex
i
, EStackIndex
j
)
Category(ies):
Lists and Matrices, Math
Description:
Computes the dot product of two vectors.
Inputs:
i, j
— EStackIndexes of two vectors are represented in one of three
ways: both as lists, both as single row matrices, or both as single
column matrices.
Outputs:
Pushes the dot product of the two vectors onto the expression stack.
Assumptions:
Arguments must be in internal-tokenized form. External-tokenized form
may cause an error throw.
Side Effects:
May expand expression stack, cause heap compression, or throw an error.
Availability:
On AMS 2.00 and higher.

Example:
/* If i is the EStackIndex of the internal-tokenized form of {1, a, b}, and j is the
EStackIndex of the internal-tokenized form of {c, 2, 3}, then */
push_dotproduct (i, j);
/* Pushes the internal-tokenized form of 2 * a + 3 * b + c onto the expression stack.
