How do I convert to Mex from Cpp using Xcode ver 10

Your SegmentBoneDP.cpp file is the source code.
If you need something that converts C++ code into MATLAB code, then you are using the wrong product family. There is no known program that converts C++ code into MATLAB code.
"The point is that I don't know the number and type of inputs the function requires since I cannot open it to see it. "
You read them out of the C++ source code.
Bness = (double *)mxGetData(prhs);
pF0 = (double *)mxGetData(prhs);
pF1 = (double *)mxGetData(prhs);
pBth = (double *)mxGetData(prhs);
pJumpConst = (double *)mxGetData(prhs);
The first parameter is Bness, and is a 2D double array.
The second parameter is F0, and it is a double scalar. It appears to be used as a weight or smoothing factor
The third parameter is F1, and it is a double scalar. It appears to be used as a weight or smoothing factor
The fourth parameter is Bth, and it is a double scalar. It is a threshold between bone and no bone.
The fifth parameter is JumpConst, and it is a double scalar. It appears to be some kind of penalty for moving from bone to no bone.
The output is an array the same size as Bness, and it is a real double 2D array.

Wow, what an inefficient communication.
As Walter has said already, the line
const int *DimsBness;
must be changed to
const mwSize *DimsBness;
This might matter other variables of the type int also.
C++ Mex files are compiled to mexmaci64 files. Of course you can neither edit these output files, not run it directly. This is the nature of compiled files. Simply put this file to a folder, which is included to your Matlab path and call it like any other function stored in an M-file:
result = BoneSegmentationDP(args)
where args are the 5 needed inputs.
"I was getting the error message that I needed to update my Xcode compiler in order to utilize the new API, that's why I used mex -compatibleArrayDims BoneSegmentationDP.cpp"
No. If you get the message, that the Xcode compiler needs an update, update the Xcode compiler. It is off-track to play around with the compatibleArrayDims flag.
