Line range

Since R2022b


    Use slreq.TextRange objects to describe lines of code in a MATLAB® code or plain-text external code file.


    There are several ways to create an slreq.TextRange object:


    expand all

    This property is read-only.

    Name of the file containing the lines of code, returned as a character vector.

    This property is read-only.

    Line range identifier, returned as a character vector. Requirements Toolbox™ generates this property value automatically for each slreq.TextRange object. If you create more than one slreq.TextRange object from the same file, each object has a unique Id property value.

    This property is read-only.

    Domain of the artifact that contains the linkable object, returned as a character vector.

    This property is read-only.

    MATLAB Function block SID, returned as a character vector.

    This property is empty for line ranges in MATLAB code files or other plain-text external code files, such as C files.

    This example shows how to create an slreq.TextRange object and link it to a requirement.

    Create an slreq.TextRange object that corresponds to line numbers 1 and 2 in the myAdd function.

    lineRange = slreq.createTextRange("myAdd.m",[1 2]);

    View the slreq.TextRange object in the MATLAB® Editor.


    Load the myAddRequirements requirement set.

    rs = slreq.load("myAddRequirements");

    Get a handle to the requirement with the summary Add u and v.

    req = find(rs,Summary="Add u and v");

    Create a link from the slreq.TextRange object to the requirement.

    myLink = slreq.createLink(lineRange,req);
