mex: Link Failed when compile C file

I have my C file and h file in one directory. but when I use mex command like

    >>mex checkPeriod.c checkPeriod.h

I got some error:

checkPeriod.h:16:24: error: mwmathutil.h: No such file or directory

mex: link of ' "checkPeriod.mexa64"' failed.

At beginning, I thought this is because a lot of other function used in this function. But when I try to compile all the files, these errors still came out. Any help??

[James Tursa]

You typically do not include header .h files in a mex command. They are generally intended to be included in the source file via a #include statement. Do you have this line in checkPeriod.c:

#include "checkPeriod.h"

If so, things are set up as I would expect, and you can try this:

mex checkPeriod.c

This is all somewhat guesswork on my part because I can't see your source files.

[Sizhe Liu]

#include "rt_nonfinite.h"
#include "checkPeriod.h"
#include "checkPeriod_emxutil.h"
#include "setinterlist.h"
#include "periodSegment.h"
#include "moveRec.h"
#include "inrec.h"
#include "checkPeriod_data.h"

This is what I find in the file, But even I use the command you mentioned. The error still come out.
