3.2.3. Matrices and Tensors

The D-SI allows data of dimension higher than that of vectors to be treated using a 'list of lists' structure. This structure allows, e.g., a matrix to be represented as shown in Table 9. Depending on the application and the preference of the user, a matrix may be represented as a list of rows or a list of columns.


#### **Table 9.** Component structure for a matrix comprising a list of lists.
