Constructor Detail

ScatteredMesh

public ScatteredMesh(RealVectors data)

Constructs the reduced mesh using the uniscaled reduction in such a way to map a mesh bounding box into the unit multidimensional cube. A new origin is associated with the mass center.

Parameters:

data - the initial mesh

ScatteredMesh

public ScatteredMesh(RealVectors data,
                     double scale)

Constructs the reduced mesh using the uniscaled reduction with a user's defined scale factor. A new origin is associated with the mass center.

Parameters:

data - the initial mesh

scale - the scale vector

ScatteredMesh

public ScatteredMesh(RealVectors data,
                     RealPointer scale)

Constructs the reduced mesh using the scaled reduction with a user's defined scale vector. A new origin is associated with the mass center.

Parameters:

data - the initial mesh

scale - the scale vector (null value mean autoscaling to the unit cube)

ScatteredMesh

public ScatteredMesh(Reduction reduction,
                     RealVectors data)

Constructs the reduced mesh using a user's defined reduction.

Parameters:

reduction - the reduction

data - the initial mesh

Method Detail

squaredDistance

public final double squaredDistance(int i,
                                    RealPointer y)

Calculates the squared distance between i-th mesh node of reduced mesh and a point prepared in reduced coordinates.

Overrides:

squaredDistance in class ReducedMesh

Parameters:

y - a point in reduced coordinates

Returns:

a squared distance

putNode

public final void putNode(int i,
                          RealPointer point)

Copies i-th node of the reduced mesh to the point specified.

Overrides:

putNode in class ReducedMesh

Parameters:

i - a node index

point - a point to copy to
