How to take derivative of a vector in matlab
WebApr 15, 2024 · More Answers (1) Take the derivative of the elements of the vector. Now each row of the matrix gives the mixing coefficients to combine the three derivatives. Note that this does not apply if the matrix contains the variable that you are taking the derivative with respect to. Sign in to comment. WebJan 27, 2024 · When you put in an array, if will calculate the difference between subsequent values. So it doesn't really find the derivative, as it find the numerical approximation of the derivative on the midpoints.
