Constructor Detail

StrictScatteredMesh

public StrictScatteredMesh(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

StrictScatteredMesh

public StrictScatteredMesh(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

StrictScatteredMesh

public StrictScatteredMesh(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)

StrictScatteredMesh

public StrictScatteredMesh(Reduction reduction,
                           RealVectors data)

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

Parameters:

reduction - the reduction

data - the initial mesh

Method Detail
