![]() Here we discuss how does MATLAB Derivative work along with appropriate syntax and respective examples. Also, the degree of differentiation or derivative can be controlled using the argument. We can calculate the derivative w.r.t the default variable or the variable we pass as an argument. ‘diff’ function is used in MATLAB to calculate the differentiation or derivative of a function. This function will calculate the ‘nth’ derivative of the input function w.r.t the variable we pass as an argument.īelow is the example where we calculate the derivative of a function using diff (f, var, n):įor our example, we will calculate the ‘2nd’ derivative w.r.t ‘t’Īs we can see, we have got the 2 nd derivative of our input function w.r.t ‘t’, as expected. Here is an example where we compute differentiation of a function using diff (f, var):įor our example, we will calculate the derivative w.r.t ‘t’Īs we can see, the derivative is calculated w.r.t. This function will find the derivative of ‘f’ w.r.t the variable in the argument. Lets us take another polynomial function defined as:įor our example, we will calculate the 2nd derivative.Īs we can see, diff (f, n) has calculated the 2 nd derivative of our input function. ![]() ![]() Here is an example where we compute ‘nth’ derivative of a function using diff (f, n): Differential or Derivatives in MATLAB Last Updated : 23 Aug, 2021 Differentiation of a function y f(x) tells us how the value of y changes with respect to change in x. This function is used to calculate the nth derivative of the input function.
