Example: Loop Control With (i).
An index value in i is used by the program "Solutions of Simultaneous Equations —
Matrix Inversion Method" in chapter 15. This program uses the looping
instructions
and
in conjunction with the indirect instructions
and
to fill and manipulate a matrix.
The first part of this program is routine A, which stores the initial loop–control
number in
i.
Program lines:
(In RPN mode)
Description:
The starting point for data input.
Loop–control number: loop from 1 to 12 in intervals of 1.
Stores loop–control number in i.
The next routine is L, a loop to collect all 12 known values for a 3
×
3 coefficient
matrix (variables
A – I ) and the three constants ( J – L ) for the equations.
