The first step is the raw data and the first difference, then the second differential in the raw data. , The point is the maximum point is the minimum point.

First, Step one of the original data for a first-order differential, and then to the original data for stage 2 differential. And, if you point to a significant value, and if that is a very small value.

The step one, first asks a step difference to the primary data, then in asks two step differences to the primary data.If, then the spot is the maximum value spot, if, then is the minimum spot.

Step one, seek first-order difference for raw data, then the raw data of second order difference. If, for maximum points, if, for the minimal value point.
