This program estimates the N-order (1rst derivative by default) derivative of a vector data Y (or the columns of a matrix) by interpolating, using INTERP1, two nearby points at each argument point X and then calculating their slope. It ignores NaNs elements.

>> dYdX = nanderivative(Y,X);

The N-order, the proximity of the interpolating points and the interpolation method (default 'spline') are optional input arguments.

Any comment will be very appreciated. (check the screenshot for an example)

v2.1 Fixed small bug with INTERP1.
1.3.0.0

Rewritten code. Mayor changes with inputs and link axes. Fixed bugs with floating point error, monotonically increasing/decreasing X and if N is not 1 do not outputs all other derivatives anymore.
