WebApr 21, 2024 · Differentiation in Matlab In Matlab, Differentiation is utilized to discover the rate of progress of an amount with respect to the quantity of other. For instance, differentiation can be utilized to compute the rate at which speed changes with the given time (which is speed increase). WebJul 9, 2024 · A derivative of a continuous function is at its base just the difference of f (x) to f (x+infinitesimal difference) divided by said infinitesimal difference. In matlab, eps is the smallest difference possible with a double precision. Therefore after each t_new we add a second point which is eps larger and interpolate y for the new points.
