WebNov 3, 2013 · Plotting and taking derivatives of functions in Matlab is perfectly easy. First you just need to use the symbolic math capabilities: syms t; x = t*exp (-3*t)+0.25*exp (-3*t); xdot = diff (x,t,1) xddot = diff (x,t,2) Then to plot these you have several options. WebOct 31, 2024 · Consider the 2nd degree polynomial: if the constraints are y' (1) = 0, and y (1) = 1; we get. Your fitting equation then becomes. Which will give shitty results since it only has one degree of freedom. But this is just an example, if you start with a 4th degree polynomial, your fitting equation will have three degrees of freedom. WebTo take the second derivative of g, enter diff (g,2) ans = -2*exp (x)*sin (x) You can get the same result by taking the derivative twice: diff (diff (g)) ans = -2*exp (x)*sin (x) In this example, MATLAB ® software automatically simplifies the answer. maria\u0027s driving school
