Instances of MATLAB fundamental classes returnfalse. Useisato test for any of these types. SeeFundamental MATLAB Classesfor more on these classes.

Examples

Define the following MATLAB class:

classdefbutton < handlepropertiesUiHandleendmethodsfunctionobj = button(pos) obj.UiHandle = uicontrol('Position',pos,...'Style','pushbutton');endendend

Test for MATLAB objects.

h = button([20 20 60 60]); isobject(h)

ans = logical 1

isobject(h.UiHandle)

ans = logical 1

Create an object that is a MATLAB numeric type:

a = pi; isobject(a)

logical 0

isa(a,'double')
