4 Information requirements

This clause specifies the information requirements for theTabular function application module.

The information requirements are specified as a set of units of functionality, application elements, and application assertions. These assertions pertain to individual application entities and to relationships between application entities. The information requirements are defined using the terminology of the subject area of this application module.

1. - A graphical representation of the information requirements is given in annex C.
2. - The mapping specification is specified in 5.1 which shows how the information requirements are met using the integrated resources of this International Standard. The use of the integrated resources introduces additional requirements which are common to application modules and application protocols.

4.1 Units of functionality

This subclause specifies the units of functionality (UoF) for the Tabular function application module as well as any support elements needed for the module definition. This part of ISO 10303 specifies the following units of functionality:

• Tabular_function

This part of ISO 10303 uses the following units of functionality:

• Maths_function;
• Maths_value.

The units of functionality and a description of the functions that each UoF supports are given below.

4.1.1 Tabular_function

The Tabular_function UoF module records the existance of a mathematical function that is a table of mathematical values.

The following application objects are used by the Tabular_function UoF:

• Banded_matrix;
• Explicit_table;
• Sparse_matrix;
• Symmetric_matrix;
• Symmetric_banded_matrix;
• Table;
• Triangular_matrix.

4.1.2 Maths_function

This UoF is defined in the Maths_function module. The following application entities from this UoF are referenced in the Tabular function module:

• Maths_function.

4.1.3 Maths_value

This UoF is defined in the Maths_value module. The following application entities from this UoF are referenced in the Tabular function module:

• Maths_value.
