Information
This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.
The output y is derived using the formula:
The function will go through the points (1,1) and (0,y0). The output will be y0 for u ≤ 0.
 |
Notes
y0(intercept) should be within the interval [0,1).s(slope) should be within the interval (0,1].- By default (
strict = true) the component will not generate events.
