WebApr 8, 2024 · Partial derivative in Matlab. To find the derivative of an expression containing more than one variable, you must specify the variable that you want to differentiate with respect to. The diff function will help … WebMATLAB provides the diff function to compute differences between adjacent array elements. This can be used to calculate approximate derivatives via a first-order forward-differencing (or forward finite difference) scheme, but the estimates are low-order estimates.
