static float [] pav::lib::Util::calcMinMax

(

float[]

data

)

[inline, static]

Calculates the minimum and maximum of a data set.

Parameters:

data

The data set. Must not be null

Returns:

An array of the form { min, max }

static float [] pav::lib::Util::quantize	(	float[]	data,
		int	steps
	)			[inline, static]

Quantizes values to a number of integers, e.g. if data is {3,4,5,6} and steps is 2 the result will be {1.0,1.0,2.0,2.0}. The lowest value in data will always map to 1.0, the largest to steps.

Parameters:

	data	The data to quantize. Must not be null
	steps	The number of steps. Must be > 0

Returns:

The quantized data

static float [] pav::lib::Util::quantize	(	float[]	data,
		int	steps,
		float	dataMin,
		float	dataMax
	)			[inline, static]

Quantizes values to a number of integers, e.g. if data is {3,4,5,6} and steps is 2 the result will be {1.0,1.0,2.0,2.0}. The lowest value in data will always map to 1, the largest to steps. Use this version if you know the min and max values of the data set.

Parameters:

	data	The data to quantize. Must not be null
	steps	The number of steps. Must be > 0
	dataMin	The minimum value in data
	dataMax	The maximum value in data

Returns:

The quantized data
