ConvexLookupPositiveConvex Lookup with positive slope; usually with fixpoint (0,y0) and fixpoint (1,1) |
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 point (1,1) and the output will be y0 for u ≤ 0.
y0
(intercept) should be within the interval [0,1).s
(slope) should be greater than 1.ConvexLookupNegative, ConcaveLookupPositive, ConcaveLookupNegative
