Method Detail

getFromQuadraticMatrix

public static Histogram getFromQuadraticMatrix(Matrix ma,
                                               double min,
                                               double max,
                                               int bins)

getHistogram

public static Matrix getHistogram(Matrix ma,
                                  Matrix maHistogramBins)

Parameters:

ma - matrix values are written into the histogram

maHistogramBins - matrix with two rows row 1: lower bins; row 2: upper bins.

Returns:

matrix with 3 rows. Row 0 lower bins, row 1: upper bins, row 2 frequency.

getHistogram

public static Matrix getHistogram(double[] arrValues,
                                  Matrix maHistogramBins)

getHistogram

public static Matrix getHistogram(Matrix maHistogramBins)

getBordersMostFreqOccBin

public static double[] getBordersMostFreqOccBin(Matrix maHistogram,
                                                int radius)

Gets the upper and lower limit of the most occupied bin.

Parameters:

maHistogram -

radius - so many bins are taken from the left and the right.

Returns:

arr[0]: lower limit, arr[1]: upper limit

getHistogram

public static Matrix getHistogram(float[] ma,
                                  Matrix maHistogramBins)

getHistogram

public static Matrix getHistogram(float[][] ma,
                                  int col,
                                  Matrix maHistogramBins)

getHistogram

public static Matrix getHistogram(Matrix ma,
                                  int numBins)

getMinOccBin

public static double getMinOccBin(Matrix maHist)

Parameters:

maHist - histogram

Returns:

the lower limit of the first occupied bin in the histogram.

getMaxOccBin

public static double getMaxOccBin(Matrix maHist)

Parameters:

maHist - histogram

Returns:

the higher limit of the last occupied bin in the histogram.

getHistogramBins

public static Matrix getHistogramBins(double dMin,
                                      double dMax,
                                      int iNumBins)

Parameters:

dMin - smallest value to put into the histogram

dMax - maximum value to be considered.

iNumBins - number of bins, between min and max.

Returns:

matrix with two rows, the lower and upper bins. The last bin is a little bit bigger than the other bins. So the highest value fits into it.

writeHistogram

public static void writeHistogram(java.lang.String sFile,
                                  Matrix hist,
                                  boolean bApppend,
                                  int digits,
                                  int totalWidth)
                           throws java.io.IOException

Throws:

java.io.IOException

histogram2String

public static java.lang.String histogram2String(Matrix hist,
                                                int digits,
                                                int totalWidth)

Parameters:

hist -

digits -

totalWidth - for one number.

Returns:
