Chapter 02.03 Differentiation of Discrete Functions

Discrete differential calculus is the study of the definition, properties, and applications of the difference quotient of a function. The process of finding the difference quotient is called differentiation. Given a function defined at several points of the real line, the difference quotient at that point is a way of encoding the small-scale (i.e., from the point to the next) behavior of the function. By fin… WebThis work is devoted to the nonasymptotic and robust fractional derivative estimation of the pseudo-state for a class of fractional-order nonlinear systems with partial unknown terms in noisy environments. ... corresponding algorithms are established in terms of integrals by employing the classical and generalized modulating functions methods ... importance of prayer in evangelismWebBy the definition of the derivative function, D(f) (a) = f ′(a) .
