kevingurney opened a new issue, #35598:
URL: https://github.com/apache/arrow/issues/35598

   ### Describe the enhancement requested
   
   Currently, the `arrow.array.<Array>` classes do not support querying the 
Null values (i.e. validity bitmap) on an Arrow array. Support for encoding Null 
values is an important part of the Arrow memory format, so the MATLAB Interface 
to Arrow should support it.
   
   There are likely multiple different APIs that the MATLAB interface should 
have to support Null values robustly. However, to focus on incremental 
delivery, we can start by adding a public `Valid` property to the 
`arrow.array.<Array>` classes, which would return a `logical` array of null 
values in the given array.
   
   ### Component(s)
   
   MATLAB
