blockConvexLookupPositive
Convex Lookup with positive slope; usually with fixpoint (0,y0) and fixpoint (1,1)
Extends from Interfaces.PartialConverters.SISO_Conversion (Partial SISO converter class with input and output conversions for lookup functions).

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.

Notes
y0(intercept) should be within the interval [0,1).s(slope) should be greater than 1.
