Derivative of a function matlab
WebJul 26, 2024 · Here are the most commonly used forms of the partial derivative function in Matlab: diff (f, x) – is the first partial derivative of f f with respect to x x ( \frac {\partial f} {\partial x} ∂x∂f or f_x f x ). diff (f, y) – … WebOct 1, 2014 · differentiate with respect to a function (3 answers) Closed 5 years ago. I want to calculate the derivative of a function with respect to, not a variable, but respect to another function. For example: g ( x) = 2 f ( x) + x + log [ f ( x)] I want to compute d g ( x) d f ( x) Can I treat f ( x) as a variable and derive "blindly"? If so, I would get
