[MATLAB] create a matlab2mex function

[asfimport]

Create a function that takes a native numeric MATLAB array and converts it into a form that can be manipulated in a C++ MEX function. Once the data is accessible inside a MEX function, it can be converted into the corresponding  arrow::NumericArray type.

Marking this as resolved.

This issue doesn't seem relevant anymore.

In the current code, each Proxy class that wraps a corresponding Arrow C++ type takes care of marshaling MATLAB types to a form that is usable by the C++ layer via a "static make method`.

Example:

arrow/matlab/src/cpp/arrow/matlab/tabular/proxy/schema.cc

Line 58 in d330d1b

libmexclass::proxy::MakeResult Schema::make(const libmexclass::proxy::FunctionArguments& constructor_arguments) {
