These terms are usually used in the world of computing to describe disk space, or data storage space, and system memory. For instance, just a few years ago we were describing hard drive space using the term Megabytes. Today, Gigabytes is the most common term being used to describe the size of a hard drive.
The precise form of the transformation law determines the type (or valence) of the tensor. The tensor type is a pair of natural numbers (n, m), where n is the number of contravariant indices and m is the number of covariant indices.
In this report, we present the design and implementation of a. Python based tensor library that is based on the MATLAB tensor-toolkit library, available from. Sandia National Labs (http://csmr.ca.sandia.gov/ tgkolda/TensorToolbox/). All the top level func-. tions are based on the library while providing similar function calls to maintain compatibility with. the MATLAB toolkit.
