Aug 23, 2021 · Differential or Derivatives in MATLAB. Differentiation of a function y = f (x) tells us how the value of y changes with respect to change in x. It can also be termed as the slope of a function. MATLAB allows users to calculate the derivative of a function using diff () method. Different syntax of diff () method are:

Example

Feb 26, 2012 · int(f,1,2) is integrate the symbolic expression f over the definite interval from 1 to 2.

Introduction to MATLAB Derivative of Function. MATLAB contains a variety of commands and functions with numerous utilities. This article is focussed on understanding how MATLAB command ‘diff’ can be used to calculate the derivative of a function. ‘diff’ command in MATLAB is used to calculate symbolic derivatives.

To determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f, 1) ans = t. Calculate the second derivative of f with respect to t: diff (f, t, 2) This command returns. ans = -s^2*sin (s*t) Note that diff (f, 2) returns the same answer because t is the default variable.

Differentiation parameter, specified as a symbolic scalar variable, symbolic function, or a derivative function created using the diff function. If you specify differentiation with respect to the symbolic function var = f(x) or the derivative function var = diff(f(x),x) , then the first argument f must not contain any of these:

Differentiation ; syms x f = sin(5*x);. The command ; diff(f). differentiates f with respect to x : ; ans = 5*cos(5*x). As another example, let ; g = exp(x)*cos(x);.

In this example, MATLAB ® software automatically simplifies the answer. However, in some cases, MATLAB might not simplify an answer, in which case you can use the simplify command. For an example of such simplification, see More Examples. Note that to take the derivative of a constant, you must first define the constant as a symbolic expression.

Use the diff function to approximate partial derivatives with the syntax Y = diff (f)/h, where f is a vector of function values evaluated over some domain, X, and h is an appropriate step size. For example, the first derivative of sin (x) with respect to x is cos (x), and the second derivative with respect to x is -sin (x).
