trimfTriangular membership function |
This information is part of the Business Simulation Library (BSL). Please support this work and ► donate.
The function returns the degree of membership using a triangular function given the real input x and the parameters lower bound of the support a
, the upper bound of the support c
and the peak or core value b
.
y := max(min((x - a) / (b - a), (c - x) / (c - b)), 0);
Functions.trimf(x, a, b, c);
Functions.trimf( 5, a=2, b=5, c=8); // 1.0 Functions.trimf( 1, a=2, b=5, c=8); // 0.0 Functions.trimf( 9, a=2, b=5, c=8); // 0.0
