How do I include a header file in MATLAB code?

I'm quite new to MATLAB and I'm trying to make a header file and include it in my MATLAB code. The header file contains a lot of constants and calculations that would be needed in the main code. I'm not sure first of all though how to save the header file, (should it be .m?) and also what's the line of code needed to include it in a MATLAB code. I'm only getting answers for including C/C++ header files in MATLAB. Apologies if this is a really basic question!

It's a really basic question but Matlab m-file syntax doesn't include the facility.
One way you can simulate it is to make the information in the header into a function that is then called by the higher level function.

The problem with that is that all the definitions in the function are local to the function. What I have done is define an M-File (NOT a function) that defines the flags: for instance an m-file called "flags.m" with the following lines:
NULL=0;
POINT=1;
LINE=2;
ARC=4;
You then call this m-file at the top of each code function that uses these flags. This works. However, if you do a dependency analysis on your code, it thinks NULL, POINT,... are Missing Files. It would be nice if there were a way to share flags and constants across a large body of code without this issue. Maybe there is and I just don't know how to do it - but a C-like header file would be ideal.
Thanks in advance for any help/advice.

"What I have done is define an M-File (NOT a function) that defines the flags:"
In MATLAB terminology what you wrote is called a script:

https://www.mathworks.com/help/matlab/matlab_prog/scripts-and-functions.html
All files with the extension .m are M-files, although this term is not really used in the documentation.
"However, if you do a dependency analysis on your code, it thinks NULL, POINT,... are Missing Files."
Make a bug report: https://www.mathworks.com/support/contact_us.html
If users do not report a bug then 1) TMW might not know about it, thus 2) it is less likely to get fixed.
