Linear subspaces

Attributes

The linearspan element supports the following attributes:

Attribute Type Default Description
basis xs:boolean - Whether or not the vectors entered by the user must be linearly independent, in addition to the other conditions, for this input field to be correct.
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.
flexvectorsize xs:boolean - When this attribute is set to true, the user must select and find out the size of the vectors in the subspace (their number of components) on his or her own. Otherwise, the size is fixed as in the solution.
maxvectorcount xs:positiveInteger | Unbounded - Maximum number of vectors that are allowed to be present in the collection of spanning vectors entered by the user in order for this field to be correct.
minvectorcount xs:nonNegativeInteger - Minimum number of vectors that have to be present in the collection of spanning vectors entered by the user in order for this field to be correct.
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.
normed xs:boolean - Whether or not the vectors entered by the user must be normed, that is, have Euclidean length one, in addition to the other conditions, for this input field to be correct.
orthogonal xs:boolean - Whether or not the vectors entered by the user must be pairwise orthogonal with respect to the standard inner product, in addition to the other conditions, for this input field to be correct.
