push_dot_mult

Declaration: void push_dot_mult (EStackIndex i , EStackIndex j )
Category(ies): Lists and Matrices, Math
Description: Pushes the element by element product of two internal tokenized
arguments onto the estack.
i
Inputs:
j
Outputs: Pushes the internal tokenized element by element product of the two
arguments onto the estack.
Assumptions: The arguments must have the same dimensions. They must be the same
length lists, or the same size matrices, or both be scalars.
Side Effects: May cause estack expansion, heap compression, or throw an error if the
arguments are invalid.
Availability: On AMS 2.00 and higher.

Example:
If m indexes the bolded tag in the list {a, 2, 0} as follows
END_TAG 0 NONNEGATIVE_INTEGER_TAG 2 1 NONNEGATIVE_INTEGER_TAG
A_VAR_TAG LIST_TAG
and n indexes the bolded tag in the list {3, 3, 3} as follows
END_TAG 3 1 NONNEGATIVE_INTEGER_TAG 3 1 NONNEGATIVE_INTEGER_TAG 3 1
NONNEGATIVE_INTEGER_TAG LIST_TAG
then
push_dot_mult (m, n);
pushes the list {a * 3, 6, 0} onto the estack such that top_estack points to the bolded tag as
follows.
END_TAG 0 NONNEGATIVE_INTEGER_TAG 6 1 NONNEGATIVE_INTEGER_TAG 3 1
NONNEGATIVE_INTEGER_TAG A_VAR_TAG MULTIPLY_TAG LIST_TAG
