The 'dy' matrix is the matrix of derivatives you want, at times corresponding ... to the derivative of dx1, dx2, and dx3 using matlab's 'gradient' function.
Aug 11, 2014 · I have a problem with numerical derivative of a vector that is x: Nx1 with respect to another vector t (time) that is the same size of x. I do the following (x is chosen to be sine function as an example): t=t0:ts:tf; x=sin(t); xd=diff(x)/ts;
Is there a function in MATLAB which can do this ? ... Assuming vector arguments, the diff function takes the differences between successive elements of the ...

Use the diff function to approximate partial derivatives with the syntax Y = diff (f)/h, where f is a vector of function values evaluated over some domain, X, and h is an appropriate step size. 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).
