mxGetPi - mxGetPiIsDeprecated error with Matlab R2018a about mexplus HOT 4 OPEN

@patrikhuber Thanks, it seems Mathworks is updating C API with explicit typed accessors. That would require mexplus implementation update.

The new C++ API looks good. Perhaps you can give that a try.

The mex command in MATLAB seems to define the macro MX_COMPAT_32 or MEX_DOUBLE_HANDLE to swith back to the old API.

If you already build MEX functions, MEX S-functions, or standalone MATLAB engine and MAT-file applications, then you should review the Do I Need to Upgrade My MEX Files to Use Interleaved Complex API? topic. To help transition your MEX files and S-functions to the interleaved complex API, MATLAB maintains a compatibility interface. To build MEX files with the compatibility interface, use the mex -R2017b flag. If your code processes complex numbers, you might notice a performance impact as MATLAB adapts your data to the interleaved complex format.
The mex command uses the -R2017b API by default. However, in a future version of MATLAB, mex will use the interleaved complex API -R2018a by default and then you need to modify your build command. Therefore, to ensure the desired behavior across versions of MATLAB, add the compatibility flag -R2017b to your build scripts.

@AchimTuran Thanks. Unfortunately, I do not have Matlab license anymore and cannot check the compatibility.
