makeNewMatlabWriter

public static MatlabWriter makeNewMatlabWriter(java.lang.String label)
                                        throws java.io.IOException

This function creates and returns a new MatlabWriter.

Parameters:

label - a keyword for the filename

Returns:

a new MatlabWriter ready to use

Throws:

java.io.IOException

finalizeMatlabWriter

public static void finalizeMatlabWriter(MatlabWriter writer)
                                 throws java.io.IOException

This function cleans up a MatlabWriter when it is no longer in use.

Parameters:

writer - the MatlabWriter to clean up

Throws:

java.io.IOException

exportScatterPlot2D

public static void exportScatterPlot2D(MatlabWriter writer,
                       cern.colt.matrix.DoubleMatrix2D values,
                       java.lang.String name)
                                throws java.io.IOException

This function writes the commands to create a scatter plot of the data in the supplied matrix. The matrix is assumed to have two columns, so that each row represents an (x, y) pair.

Parameters:

writer - the MatlabWriter to write to

values - an n x 2 matrix containing the data to plot

name - the variable name to write to

Throws:

java.io.IOException

exportScatterPlot3D

public static void exportScatterPlot3D(MatlabWriter writer,
                       cern.colt.matrix.DoubleMatrix2D values,
                       java.lang.String name)
                                throws java.io.IOException

This function writes the commands to create a 3-D scatter plot of the data in the supplied matrix. The data is assumed to have three columns, so that each row represents an (x, y, z) triple.

Parameters:

writer - the MatlabWriter to write to

values - an n x 3 matrix containing the data to plot

name - the variable name to write to

Throws:

java.io.IOException

exportScatterPlot2D

public static void exportScatterPlot2D(MatlabWriter writer,
                       cern.colt.matrix.DoubleMatrix2D values,
                       java.lang.String name,
                       int[] labels)
                                throws java.io.IOException

This function writes the commands to create a scatter plot of the data in the supplied matrix. The matrix is assumed to have two columns, so that each row represents an (x, y) pair. Additionally the points are plotted with different markers and colors for each class.

Parameters:

writer - the MatlabWriter to write to

values - an n x 3 matrix containing the data to plot

name - the variable name to write to

labels - the classes for each data point

Throws:

java.io.IOException

exportScatterPlot3D

public static void exportScatterPlot3D(MatlabWriter writer,
                       cern.colt.matrix.DoubleMatrix2D values,
                       java.lang.String name,
                       int[] labels)
                                throws java.io.IOException

This function writes the commands to create a 3-D scatter plot of the data in the supplied matrix. The data is assumed to have three columns, so that each row represents an (x, y, z) triple. Additionally the points are plotted with different markers and colors for each class.

Parameters:

writer - the MatlabWriter to write to

values - an n x 3 matrix containing the data to plot

name - the variable name to write to

labels - the classes for each data point

Throws:

java.io.IOException
