Method Detail

getWeights

public double[][][] getWeights()

Returns current reference vector weights. Weights are returned as a 2D grid of vectors.

Returns:

reference vector weights

getUnit

public int[] getUnit(double[] v)

Returns indices of grid point whose reference vector is closest to a given vector. Point is returned as a 2D integer array.

Parameters:

v - vector

Returns:

point closest to v

Throws:

java.lang.IllegalArgumentException - if v mismatches dimensionality of IGG

getUnits

public int[][] getUnits()

Returns indices of grid points from reference vectors. Points is returned as an array of 2D integer arrays.

Returns:

grid points corresponding to reference vectors

getRowDimension

public int getRowDimension()

Returns the number of rows in this map.

Returns:

the number of rows in this map

getColumnDimension

public int getColumnDimension()

Returns the number of columns in this map.

Returns:

the number of columns in this map
