kevingurney opened a new pull request, #35551:

> **Warning** This pull request is dependent upon #35495 and #35491. We will
rebase and mark as ready for reviewer once that one is merged.
### Rationale for this change
In order to allow clients to write generic code for different concrete
`arrow.array.Array` subclasses in MATLAB, it would be helpful to have one
generic `toMATLAB` method. `toMATLAB` would convert the `arrow.array.Array`
into a corresponding MATLAB type.
For example, `arrow.array.Float64Array` would be converted to a MATLAB
`double` array.
```matlab
>> doubleMatlabArray = toMATLAB(float64ArrowArray) % Convert the
arrow.array.Float64Array to a MATLAB double array
```
### What changes are included in this PR?
1. Added a public `toMATLAB` method to the `arrow.array.Array` superclass.
Example of using `toMATLAB` on an `arrow.array.Float64Array`:
```matlab
>> arrowArray = arrow.array.Float64Array(1:10)
arrowArray =
[
1,
2,
3,
4,
5,
6,
7,
8,
9,
10
]
>> matlabArray = toMATLAB(arrowArray)
matlabArray =
1
2
3
4
5
6
7
8
9
10
>> class(matlabArray)
ans =
'double'
```
### Are these changes tested?
1. Yes, we added tests for `toMATLAB` to `tFloat32Array.m` and
`tFloat64Array.m`.
2. This was qualified on a Debian 11 machine.
### Future Directions
1. Move the `toMATLAB` tests to the shared test utility class (i.e. #35537).
### Notes
1. Thanks to @sgilmore10 for her help with this pull request!
