How do you find the derivative of a discrete function?

We define the discrete derivative of a function f(n), denoted ∆nf(n), to be f(n + 1) − f(n). This operator has some interesting properties. = 2n + 1. Notice that this is exactly what we get if we just do ∆n(n2)=(n + 1)2 − n2 = 2n + 1.

Can Matlab compute derivative?

To find the derivative of g for a given value of x , substitute x for the value using subs and return a numerical value using vpa . Find the derivative of g at x = 2 . In this example, MATLAB^® software automatically simplifies the answer.

What is derivative in discrete math?

The term discrete derivative is a loosely used term to describe an analogue of derivative for a function whose domain is discrete. The idea is typically to define this as a difference quotient rather than the usual continuous notion of derivative, which is defined as a limit of a difference quotient.
