%MAKE_EMDC  Compiles the C codes for Empirical Mode Decomposition
%
% Note: The compilation can fail on some systems (e.g. MacOS) if Matlab cannot find the C compiler.
% In this case, you should either install a C compiler or check Matlab configuration.
% The configuration files for compilation are mexopts.sh (Unix / MAC OS) and mexopts.bat (Windows)
% use "mex -setup" to choose a configuration file (Unix) or select a compiler (Windows).
