Vektoren

Eingabefelder für Vektoren können mit dem Eingabetyp vector im input Element erzeugt werden.

Ein Vektor kann entweder aus Zahlen oder aus Ausdrücken bestehen. Diese beiden Eingabetypen dürfen innerhalb eines Vektors nicht gemischt werden.

Example

<p>
    Geben Sie den ersten Standardbasisvektor im Raum <m>\mathbb{R}^3</m> ein:
</p>
<p>
    Antwort: <input>
        <vector>
            <number>1</number>
            <number>0</number>
            <number>0</number>
        </vector>
    </input>
</p>

Attribute

Das vector Element unterstützt die folgenden Attribute:

Attribut	Typ	Standardwert	Beschreibung
credits	xs:nonNegativeInteger	1	Number of credit points the user gets awarded for this input value. If this input value is part of another input value (such as a vector or a set), then the credits of the child input values are interpreted as relative weights. That means the top level input value has the absolute credits as specified in its credits attribute and each child input value contributes to this number its credits attribute value divided by the sum of all credits attribute values of all children.
defaultsize	xs:positiveInteger | Auto	-	Initial number of components in this vector that are already there when the user loads the page. When this attribute is set to auto, the default size is the size of the first vector written as solution in this input value element.
maxsize	xs:positiveInteger | Unbounded	-	Maximum number of components in this vector or the special value "unbounded", which means that there is no upper bound on the size of the vector.
minsize	xs:positiveInteger	-	Minimum number of components in this vector.
model	xs:Name	-	Name of the model to use for this input value. If this attribute is not set, the input model associated to the input field containing this input value is used.
type	VectorType	-	Type of the vector (column vector or row vector).
