Differentiation in Matlab is used to find the rate of change of a quantity w.r.t the other. For example, differentiation can be used to calculate the rate at which velocity changes with time (which is acceleration). Using differentiation, we can also find the rate at which ‘x’ changes w.r.t ‘y’. how much is one dollar in venezuelan bolivarNettet19. mar. 2012 · To obtain the derivative of a polynomial, which is itself a polynomial, use Matlab's polyder() function.
