I wish to use gsl in oder to perform the derivative of a data set contains in an one dimensional array. It seems that gsl numerical differentiation estimate the derivative of function only.
Does anyone as an idea?
Do I have to do it "by hand" using for example u'(x) = ( u(x+h) - u(x) ) / h?
Thanks in advance,
