isvalid

Class: vrfigure

(To be removed) Check validity of vrfigure object handles

vrfigure.isvalid will be removed in a future release. For more information, see Version History.

Syntax

valid_handles = isvalid(vrfigure_vector)


Description

valid_handles = isvalid(vrfigure_vector) detects whether the vrfigure handles are valid.

Input Arguments

figure_vector — Virtual reality figure vector

array of vrfigure object handles

Virtual reality figure vector, specified as a vrfigure object.

Output Arguments

valid_handles — Valid vrfigure object handles

logical array

Virtual reality figure image, captured as a logical array. The array that contains a 1 where the vrfigure handles are valid and returns a 0 where they are not.

Examples

Check Validity of Figure Handles

Check whether the figure handles of the vrfigure object are valid. The first check shows that the figure handle is valid, but the second check shows that the handle is invalid because the figure is closed.

myworld = vrview('vrpend');
f = vrfigure(myworld);
firstCheck = isvalid(f)

firstCheck = logical
   1

close(f)

secondCheck = isvalid(f)

secondCheck = logical
   0

Version History

Introduced before R2006a

R2023b: To be removed

The vrfigure.isvalid will be removed in a future release. Instead, use sim3d classes and Simulation 3D blocks in Unreal Engine Scenario Applications to interface MATLAB^® and Simulink^® with the Unreal Engine^® 3D simulation environment.
