createMatlabMatrixFile

public static void createMatlabMatrixFile(java.lang.String comments,
                                          Instances data,
                                          java.lang.String filename)

Output instances as simple matlab matrix file

Parameters:

comments - the comments to be put into the file

data - the data to be output

filename - the filename to create

plotInstancesAsMatlabLineGraph

public static void plotInstancesAsMatlabLineGraph(java.lang.String comments,
                                                  java.lang.String title,
                                                  java.lang.String yAxisLabel,
                                                  java.lang.String xAxisLabel,
                                                  Instances data,
                                                  java.lang.String filename,
                                                  java.lang.String xAxisAttName)

Useful function for plotting the a data set of instances as a Matlab line graph. Each attribute is treated as a different line on the graph. The attribute names are used as the legends for each line.

Parameters:

comments - string used to describe experiment this will be commented out

title - the tile of the line plot

yAxisLabel - the name that you want to give the y-axis on the plot

xAxisLabel - the name that you want to give the x-axis on the plot

data - the instances to be plotted

filename - the filename (with directory path) to call the matlab '.m' file

xAxisAttName - string name of the attribute in the data which will be used for the x-axis

commentOutText

public static java.lang.String commentOutText(java.lang.String text)

This is a stupid function that puts in Matlab comments into a region of text. It looks for carriage returns so that it can insert comments for each new line.

Parameters:

text - the text to be converted

Returns:

the text with added comments.
