19 мая 2014 г. · Hi I have a number of points (experimental data) plotted as an x-y plot. I want to generate the derivative of y w.r.t x from this plot.

dy = derivative(x,y) returns the derivative of a set of data, vs. (which are stored in y and x ). dy stores the derivative of y vs. x at every point in x.
