File Information
Description

Interactive differentiation for time- series signals, with sliders that allow you to adjust the derivative order, smooth width, and scale expansion continuously while observing the effect on your signal dynamically. Run InteractiveDerivativeTest to see how it
works. For more information see http://www.wam.umd.edu/~toh/spectrum/InteractiveDerivative.htm.

The sliders used in this program do not work in recent version of Matlab. I've now uploaded a new keypress-operated version that performs interactive smoothing, derivatives, and peak sharpening. See http://www.mathworks.com/matlabcentral/fileexchange/32075-isignal

Slider function modified by commenting out lines 337 and 373
to prevent crash on Matlab 2008 and 2009.
