Apr 08, 2020 · To find the derivatives of f, g and h in Matlab using the syms function, here is how the code will look like syms x f = cos(8*x) g = sin(5*x)*exp(x) h =(2*x^2+1)/(3*x) diff(f) diff(g) diff(h) Which returns the following ( You can decide to run one diff at a time, to prevent the confusion of having all answers displayed all at the same time )

18.04.2013 · Cancel. Copy to Clipboard. Call polyfit to generate your polynomial (if you don't already have a polynomial) Call polyder to get derivative of your fitted line. Call polyval with your original X values to get the Y values of your derivative and plot that with hold on so it doesn't erase your original plot.

Now that we have refreshed our concepts of differentiation, let us now understand how it is computed in MATLAB. Syntax of derivative: diff (f) diff (f, var) diff (f, n) diff (f, var, n) Examples of Derivative of Function in MATLAB. Now we will understand the above syntax with the help of various examples. 1. diff (f)

Jan 14, 2015 · S.t is the time vector and S.I is the current vector in each time in S.t . (both should be in the same length N ). Now, if you want to approximate the derivative: dt = diff (S.t); % dt is the time intervals length, dt is N-1 length. dI = diff (S.I); derivative = dI./dt; %derivative is memberwise division of dI by dt plot (t (1:end-1),derivative); % when you plot both vector should be in the same length: % t (1:end-1) is the same as t except the last coordinate.

May 19, 2014 · dydx = diff ( [eps; y (:)])./diff ( [eps; x (:)]); Both produce a column vector, so you may have to transpose it if x is a row vector in order to plot it with the others. UPDATE — (24 Mar 2019 00:30) A much more accurate approach would be: dydx = gradient (y (:)) ./ gradient (x (:));
