Diff. Sigmoidal MF - Difference of two sigmoids membership function in Simulink software

Description

The Diff. Sigmoidal MF block implements a membership function in Simulink based on the difference between two sigmoids. The two sigmoid curves are given by

where k=1,2. The parameters a₁and a₂ control the slopes of the left and right curves. The parameters c₁ and c₂ control the points of inflection for the left and right curves. The parameters a₁ and a₂ should be positive.
