Walter Roberson on 3 Sep To get trials of anything other than the newest version, you need to contact Mathworks Sales. I do not know if they will be willing to give a trial of a version that old, especially since they know you would not be purchasing later releases since the later releases will not run on the system.

Walter Roberson on 2 Aug Data compression and decompression slow down all save operations and some load operations. In most cases, the reduction in file size is worth the additional time spent.

In some cases, loading compressed data actually can be faster than loading uncompressed data. For example, consider a block of data in a numeric array saved to both a 10 MB compressed file and a MB uncompressed file. Loading the first 10 MB takes the same amount of time for each file. Loading the remaining 90 MB from the uncompressed file takes nine times as long as loading the first 10 MB.

Completing the load of the compressed file requires only the relatively short time to decompress the data. The amount of data in each item is small relative to the complexity of its container. For example, simple numeric arrays take less time to compress and uncompress than cell or structure arrays of the same size.

Compressing arrays that result in an uncompressed file size of less than 3 MB offers limited benefit, unless you are transferring data over a network. The time required to load part of a variable from a Version 7.

Each chunk that contains any portion of the data you want to load must be fully uncompressed to access the data. Rechunking your data can improve the performance of the load operation.
