DER estimates the derivative of an array X with an ...

DER by Carlos Adrian Vargas Aguilera estimates the DER by Carlos Adrian Vargas Aguileraivative of an array X with an argument T: dX/dT, evaluating the slope of a polynomial fit of elements "close" to every point.
This "closeness" is controlled by an optional input called window width, in turn this controls the smoothness.
Syntax:
dxdt = DER 1.0(X, DT);
, where X is a time series and DT its sampling interval.
dXdT = DER [der1.0.exe](X, T);
, if T is not uniform.
Other optional inputs are:
- the window width (W)
- the polynomial fit degree (DEG)
- the padding (PAD) % to improve DER - 0MBivatives at edges
Besides, the error of the dXdT estimate may be obtained.
Demands:
• MATLAB 7. 7 or higher
