Method Detail

set

public final void set(double[] data)

Initialize the array with given values.

Parameters:

data - initial data

set

getMin

public double getMin()

calculate the minimum value in the data.

Returns:

minimum of all data points

getMax

public double getMax()

calculate maximum value in the data

Returns:

maximum value of the data.

getBinSuggestion

public int getBinSuggestion()

copy

public void copy(DataVector vec)

isOrdered

public boolean isOrdered()

findBin

public int findBin(double value)

findBin

public int findBin(double value,
                   int start)

mult

public void mult(double norm)

Multiplies the whole data with the provided number

Parameters:

norm - multiplication factor

divide

public void divide(double norm)

Divides the content of the vector by given number.

Parameters:

norm -

getCumulative

public DataVector getCumulative()

Returns cumulative integral of the vector.

Returns:

getMean

public double getMean(DataVector xvec)

Calculates the normalized mean with the given axis.

Parameters:

xvec -

Returns:

getMean

public double getMean()

Calculates the mean of the vector.

Returns:

mean value

getRMS

getLowEdge

public double getLowEdge(int bin)

Returns the low edge for the bin which is determined by bin width.

Parameters:

bin - bin number

Returns:

the low edge for the bin.

getHighEdge

public double getHighEdge(int bin)

getBinWidth
