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.

The Derivative block approximates the continuous derivative of the continuous input signal u with respect to the simulation time t.

To find the derivative of g for a given value of x, substitute x for the value using subs and return a numerical value using vpa. Find the derivative of g at x = 2.

Apr 14, 2021 · Hello, I'm using Matlab 2012 and would need the numerical derivative of a function. What is the Malab command for that ? Thank you in advance

Mar 17, 2019 · As a part of analysis, I need to estimate the first derivative using central differences and obtain the maximum gradient. Because my data is too noisy, I need to filter it before taking the …

Feb 6, 2023 · The gradient funciton returns an estimate of the derivative with the length (and more generally, size) of the output being the same as the input. (It can also be used to calculate spatial …
