WebApr 2, 2024 · This seems to be the correct solution to the question I asked. The reason I used y1 and y2 is due to the physics of the problem. The potential energy is related to the height of the object. q1 and q2, the degrees of freedom, are not necessarily y1 and y2. WebJan 14, 2015 · Assume you have a structure S,. 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.

WebApr 12, 2024 · Use diff when there are vectors instead of scalars. In this case, they are scalars, you can take the difference using a '-' math operator. The 2nd argument in the diff function has been used incorrectly. It represents the number of times the derivative or difference to be done. WebTo determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f,1) ans = t. Calculate the second derivative of f with respect to t: diff (f,t,2) This command returns. ans = -s^2*sin (s*t) Note that diff (f,2) returns the same answer … This MATLAB function performs algebraic simplification of expr.
