See the complete set of rules in Find Symbolic Variables in Expressions, Functions, and Matrices. In the preceding example, diff(f) takes the derivative of f with respect to t because the letter t is closer to x …

Aug 9, 2025 · 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). You can use diff to approximate these derivatives.

This MATLAB function differentiates f with respect to the symbolic scalar variable in the definition of f.

For differentiation, you can differentiate an array of data using gradient, which uses a finite difference formula to calculate numerical derivatives. To calculate derivatives of functional expressions, you …

For in-depth information on taking symbolic derivatives see Differentiation. Expressions with One Variable To differentiate a symbolic expression, use the diff command. The following example …

Differentiation This example shows how to analytically find and evaluate derivatives using Symbolic Math Toolbox™. In the example you will find the 1st and 2nd derivative of f (x) and use these …

This MATLAB function returns the derivative of the polynomial represented by the coefficients in p,

G — Functional derivative symbolic function | vector of symbolic functions Functional derivative, returned as a symbolic function or a vector of symbolic functions. If input y is a vector, matrix, or an …

Differentiation Analytically find and evaluate derivatives using Symbolic Math Toolbox™. In the example you will find the 1st and 2nd derivative of f (x) and use these derivatives to find local maxima, minima …

S = dsolve(eqn) solves the differential equation eqn, where eqn is a symbolic equation. Use diff and == to represent differential equations. For example, diff(y,x) == y represents the equation dy/dx = y. …
