These functions compute membership degrees of numeric fuzzy sets with
triangular or raised-cosine shape. These functions are deprecated.
Please use triangular() or raisedcosine() functions instead.

A numeric vector of membership degrees of x to a fuzzy set with the shape
determined with lo, center, hi.
A numeric vector to be transformed.
A lower bound (can be -Inf).
A peak value.
An upper bound (can be Inf).
