Since R2022a

Syntax

RequirementRows = getRequirementRows(reqTable)

RequirementRows = getRequirementRows(reqTable,level)

Description

RequirementRows = getRequirementRows(reqTable) returns the top-level requirement rows of the Requirements Table block specified by reqTable.

RequirementRows = getRequirementRows(reqTable,level) returns the requirement rows from the top-level to the level specified by level. (since R2026a)

Examples

Retrieve Requirements from a Requirements Table Block

Retrieve the RequirementsTable object from a model named myModel.

table = slreq.modeling.find("myModel");

Retrieve the requirements as an array of RequirementRow objects.

row = getRequirementRows(table);

Get All Requirement Rows in Requirements Table Block

Since R2026a

This example shows how to get all of the requirement rows in a Requirements Table block.

Load the temporal_logic_operators_example model.

model = "temporal_logic_operators_example";
load_system(model)

Find the Requirements Table block in the model.

table = slreq.modeling.find(model);

The requirement row hierarchy in the Requirements Table block is two levels deep. Get all of the requirement rows in the model.

allRows = getRequirementRows(table,2)

allRows=1×6 RequirementRow array with properties:
    Actions
    Duration
    ChildEvaluation
    RowType

    Summary

Input Arguments

reqTable — Requirements Table block

RequirementsTable object

Requirements Table block, specified as a RequirementsTable object.

level — Lowest level of requirement rows to return

integer

Lowest level of requirement rows to return, specified as an integer.

To return the requirement rows in the top level and their children, specify level as 2. If you specify a value for level that is greater than the number of hierarchy levels in the Requirements Table block, the function returns all the requirement rows.

Output Arguments

RequirementRows — Requirements

array of RequirementRow objects

Requirement rows in the Requirements Table block, returned as an array of RequirementRow objects.
