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. WebMATLAB provides the diff function to compute differences between adjacent array elements. This can be used to calculate approximate derivatives via a first-order forward-differencing (or forward finite difference) scheme, but the estimates are low-order estimates.
