You cannot call a c++ file directly. At first you have to write a so called Mex-wrapper: this is the function "mexFunction", which is called as entry point. Then compile the file using the mex command.

See https://www.mathworks.com/help/matlab/matlab_external/introducing-mex-files.html.

after successfully compiling the c++ code in matlab, are you able to call it? If not, how are you supposed to access it in matlab?
