The analysis.m Script
The analysis.m script, found in the analysis directory, consumes the statistics files that the compressor outputs and generates various plots based on them. Once opened, just evaluate the entire notebook (for large files, or large numbers of files, this may take a fairly long time). By default, the notebook will use all files in the current directory with the .st extension, though specific files can be selected by changing the value of statsFiles in the Parameters section.
Test Data
The test data used to generate the Data & Results section can be obtained (on Linux) by running the getFiles.sh script. This downloads a collection of test files with various types of data (e.g. English text), and cuts each down to 128KiB for comparison. Once this has been done, the genStats.sh script can be run to compress these files and generate statistics for various configurations of the compressor; what these configurations are can be specified in a straightforward way by modifying the script. The genStats.sh script also checks that the extracted file is identical to the original, and reports if it is not.
