push_def_int
Declaration:
void
push_def_int
(EStackIndex
i
, EStackIndex
vi
, EStackIndex
j
,
EStackIndex
k
)
Category(ies):
Math
Description:
Pushes onto the estack the definite integral of the expression indexed
by
i
, integrated with respect to the variable indexed by
vi
, from the
lower limit indexed by
j
to the upper limit indexed by
k
. If invoked via
push_internal_simplify
,
vi
and
i
are simplified to deepest variable.
Moreover,
i
is simplified under the influence of a temporary such that
vi
>
j
and
vi
<
k
when
j
<
k
.
Inputs:
i
— Index of the top tag of an internally-simplified algebraic
expression, a comparison, or an aggregate thereof.
vi
— Index of the top tag of a variable.
j, k
— Indices of the top tags of internally-simplified algebraic
expressions or aggregates thereof.
Outputs:
None
Assumptions:
None
Side Effects:
None
Availability:
On AMS 2.02 and higher.
