Hello

I'm a beginner in using MEX function, I just have code I purchased from internet and I want to use it inside matlab but when I use MEX function I get such errors

files I use are
SAT_Filter.cpp
SAT_DE.cpp
SAT_Filter.cpp
SAT_Kepler.cpp
SAT_RefSys.cpp
SAT_Time.cpp
SAT_VecMat.cpp
RTOD.cpp

and header files :
SAT_Force.h
SAT_DE.h
SAT_Filter.h
SAT_Kepler.h
SAT_RefSys.h
SAT_Time.h
SAT_VecMat.h
Sat_const.h


>> mex -v SAT_Filter.cpp SAT_DE.cpp SAT_Filter.cpp SAT_Kepler.cpp SAT_RefSys.cpp SAT_Time.cpp SAT_VecMat.cpp RTOD.cpp
