cstdlib: No such file or directory

Hello, I am trying to compile mex function

clear
clc
mex vfi_mex.c -I"../CRoutines" 

But then I got an error message as below

..\CRoutines/blitz/compiler.h:132:19: fatal error: cstdlib: No such file or directory

How can I solve this?

Thanks in advance

That is the C++ standard library. Make sure your C++ is fully installed.
