kevingurney opened a new issue, #35693:
URL: https://github.com/apache/arrow/issues/35693
### Describe the enhancement requested
This is a follow up to #35676 and #35598 .
To allow users to clearly specify which values in an input MATLAB array
should be treated as null values when constructing an `arrow.array.Array`, it
would be helpful to add a `Valid` name-value pair to the `arrow.array.Array`
superclass constructor.
This name-value pair would correspond to the public `Valid` property which
encodes the validity bitmap (i.e. null values) in an `arrow.array.Array`
(proposed in #35598). This name-value pair would override any null detection
heuristics (i.e. it would override the behavior of `DetectNulls` and
`NullDetectionFcn`).
Adding this name-value pair would provide clients with a way to
unambiguously control null value handling behavior when constructing
`arrow.array.Array` objects.
**Example:**
```matlab
>> matlabArray = double([1, -1, -1, 3, 4, 5])'
matlabArray =
1
-1
-1
4
5
>> A = arrow.array.Float64Array(matlabArray, Valid=logical([true false,
false, true, true]))
A =
[
1,
null,
null,
4,
5
]
```
