public interface UnivariateDifferentiableFunction extends UnivariateFunction
This interface represents a simple function which computes both the value and the first derivative of a mathematical function. The derivative is computed with respect to the input variable.
UnivariateDifferentiableFunction classes compute both the
value and the first derivative of the function.
t- function input value
DimensionMismatchException- if t is inconsistent with the function's free parameters or order
