maxP2P()

void maxP2P	(	data_t *	dat,
		data_t *	big,
		data_t *	maxpp,
		int	sz,
		int	t
	)

find the maximum peak-to-peak value at each point

The peak-to-peak amplitude of each montonically increasing or decreasing segment is compared. The big scratch array is divided into 3 sections: the value at the previous time, whether the value was increasing or decreasing, and the value of the last extremum. Extremum are detected when the direction of change reverses. Repeated values are ignored.

Parameters

dat	current data frame
big	scratch data [previous val;direction;extremum]
maxpp	current maximum peak-to-peak
sz	slice size
