I have made a simple spline(x,y) of 4 datapoints and I want to differentiate it.
I can't get it to work; I have tried fntlr, fnder ect.
Can anyone help?

What program are you using? Don't bother with built in functions, just use a finite different scheme and find it yourself. Are you familiar with those?
