Description Usage Arguments Details Value Note Author(s) See Also Examples
This function computes the locations of the extrema of the cusp catastrophe potential function.
1 | cusp.extrema(alpha, beta)
|
alpha |
(single) value of normal/symmetry factor |
beta |
(single) value of bifurcation/splitting factor |
The locations are determined by computing the solutions to the equation
α+β * X - X^3 = 0.
Ordered vector with locations of extremes.
Use Vectorize
to allow for array input.

cusp.extrema(2,3)
# using vectorize to allow for array input;
# returns a matrix with locations in each column
