The VectorNorm(V) calling sequence displays a Maplet application that returns the vector norm of V.

A definition of the vector norm is given in the Maplet application.

By using the Norm (Select from list or enter non-negative number) combo box, control the vector norm returned.

By using the Vector has real values check box, control the algorithm used to calculate the vector norm. If the vector has real entries, a faster algorithm can be used. The default value is determined by using the value of $\mathrm{has}\left(V\,\mathrm{I}\right)$, which returns true if V has complex entries. That is, it is selected, by default, only if V has no complex entries.

Note: If Vector has real values is selected and the vector has any complex entries, an incorrect result may be returned.

By using the Evaluate result check box, control whether the Maplet application returns the vector norm of V or the calling sequence required to calculate the vector norm in the worksheet. The default behavior is to evaluate the result, that is, return the norm.

The VectorNorm sample Maplet worksheet demonstrates how to write a Maplet application that functions similarly to the Maplet application displayed by this routine.
