08.03.2009 · A simple method is to compute the change in f over a small value for each point of the derivative you're interested in. For example, to compute ∂f/∂x, you could use this: epsilon = 1e-8 ∂f/∂x (x, y, z) = (f (x+epsilon,y,z) - f (x-epsilon, y, z))/ (epsilon * 2); The other partials would be similar in y and z.

Mar 09, 2009 · Now in a DO-WHILE loop: 1- divide h by 2 (or by 10, the important thing is to make it smaller) 2- calculate again the difference quotient with the new value of h, store this in f2 3- set diff = abs (f2-f1) 4- assign f1 = f2 5- repeat from point 1 while (diff>epsilon) You can finally return f1 (or f2) as the value of your f' (a)

Discrete calculus or the calculus of discrete functions, is the mathematical study of incremental change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations. The word calculus is a Latin word, meaning originally "small pebble"; as such pebbles were used for calculation, the meaning of the word has evolved and today usually means a method of computation. Meanwhile, calculus, originally called infinite…

A finite difference is a mathematical expression of the form f (x + b) − f (x + a).If a finite difference is divided by b − a, one gets a difference quotient.The approximation of derivatives by finite differences plays a central role in finite difference methods for the numerical solution of differential equations, especially boundary value problems.
