push_exponentiate

Declaration: void push_exponentiate (EStackIndex i , EStackIndex j )
Category(ies): Math
Description: Pushes the internally-simplified result of (expression i )^(expression j ) onto
the estack. If expression i is a square matrix: pushes the same-size identity
matrix if j indexes a zero; pushes the iterated matrix product if j indexes a
positive whole number; pushes the inverse matrix or its iterated matrix
product if j indexes a negative whole number.
Inputs: i, j — Indices of the top tags of internally-simplified algebraic
Outputs: None
Assumptions: None
Side Effects: None
Availability: On AMS 2.02 and higher.
TI-89 / TI-92 Plus
Differences: None

Example:
void push_distrib_base_over_tail (EStackIndex bas, EStackIndex tail)
/* tail indexes a sequence of expressions terminated by END_TAG.
Pushes onto the estack a similar sequence of expression bas raised to
the expressions in tail.
*/
{ if (END_TAG == ESTACK (tail))
push_quantum (END_TAG);
else
{ push_distrib_base_over_tail (bas, next_expression_index (tail));
push_exponentiate (bas, tail);
}
