Field Detail

histograms

public MultidimensionalHistogram[][] histograms

The histogram data

Constructor Detail

BlockHistogramModel

public BlockHistogramModel(int blocks_x,
                           int blocks_y,
                           int... nbins)

Construct with the given parameters

Parameters:

blocks_x - the number of blocks in the x-direction

blocks_y - the number of blocks in the y-direction

nbins - the number of bins in each dimension for the histograms

Method Detail

toSingleHistogram

public MultidimensionalHistogram toSingleHistogram()

Returns:

a flattened version of the histogram array formed by concatenating the histograms of all the blocks in scan order.

reset
