calculates the partial derivative ∂ f / ∂ t. The result is ans = s*cos (s*t) To differentiate f with respect to the variable s , enter diff (f,s) which returns: ans = t*cos (s*t) If you do not specify a variable to differentiate with respect to, MATLAB chooses a default variable.

Use of ‘polyder ()’ command in Matlab. To calculate derivatives of polynomials in Matlab, you need to understand the logic of definition of polynomials with vectors. For example we defined two of vectors as shown in green box above called as ‘a’ and ‘b’. For instance the vector ‘a’ stands for the polynomial of 4x^5+6x^4+5x^3+8x^2+9x+3.

Aug 23, 2021 · MATLAB allows users to calculate the derivative of a function using diff() method. Different syntax of diff() method are: f’ = diff(f) f’ = diff(f, a) f’ = diff(f, b, 2) f’ = diff(f) It returns the derivative of function f(x) wrt variable x.
