Differentiation function, specified as a symbolic function or a vector, matrix, or multidimensional array of symbolic functions. The argument y can be a function of one or more independent variables. If y is a vector of symbolic functions, functionalDerivative returns a vector of functional derivatives with respect to the functions in y, where all functions in y must depend on the same ...
Differentiation. To illustrate how to take derivatives using Symbolic Math Toolbox™ software, first create a symbolic expression: syms x f = sin(5*x);.
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:
28.03.2020 · 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.
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:
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.
