Appendix A: System Routines - Math 841 raise_to_top Declaration: void raise_to_top (EStackIndex i) Category(ies): Math Description: Replaces the top expression on the estack with the simplified result of (expression i)^(top expression). If expression i is a square matrix: pushes the same-size identity matrix if top_estack indexes a zero; pushes the iterated matrix product if top_estack indexes a positive whole number; pushes the inverse matrix or its iterated matrix product if top_estack indexes a negative whole number. Inputs: i, j - Indexes to the top tags of internally-simplified algebraic expressions, algebraic comparisons, or aggregates thereof. Outputs: None Assumptions: None Side Effects: None Availability: On AMS 2.02 and higher. TI-89 / TI-92 Plus Differences: None See Also: push_dot_exponentiate, push_exponentiate, replace_top2_with_pow, push_sqrt, push_square, push_reciprocal, replace_top_with_reciprocal Example: void push_increment_degree (EStackIndex power, EStackIndex inc) /* Pushes onto the estack factor_base (power) ^ (inc + factor_deg(power)) */ { push_sum (inc, factor_exponent_index (power)); raise_to_top (factor_base_index (power)); } TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
