Instruction 101 Function Generator
Expression:
Space Requirement: 1 line x 6 column Location Requirement: Middle, Right rail
Function:
The Function Generator is used to compute a value f(x) for a given value x stored in Register A.
The value f(x) is then stored into Register C. The computed value is derived based upon a linear
equation as represented by several points in a table of consecutive registers (of size 2n)
beginning with Register B. The table of points represents the X and Y values of a plotted linear
graph. The first half of registers represents the X axis plot points. The second half represent the
Y axis plot points.
