Constructors with single output cc4m_logo_inline
IDFCNS-3
TitleEvery constructor shall have exactly one output.
PriorityMandatory
Severity level5
DescriptionEvery constructor shall have exactly one output: an object of the class.
RationaleA second constructor output is unusual, so will be unexpected for readers of the code.
ExceptionThe second output may be used to indicate whether or not construction was successful. Alternatively, this is done by either throwing an error or by using a property for this.

Avoid:

classdef Computer
    methods
        function [obj, out2] = Computer(in)
            obj.value = in;
            out2 = 2 * in;
        end
    end
end

Instead use:

classdef Computer
    methods
        function obj = Computer(in)
            obj.value = in;
        end
    end
end
