Class CompressionStatistics

java.lang.Object
org.apache.sysds.runtime.compress.CompressionStatistics
public class CompressionStatistics extends Object
Compression Statistics contain the main information gathered from the compression, such as sizes of the original matrix, vs the compressed representation at different stages of the compression.
