I have a compiled m file using runtime library v7.6. Which version of matlab created it?

I need to modify a very old m file and compile it (as a com DLL) so that it will use runtime library v7.6 (user base still using this library). Which version of Matlab I need to use so that the compiled file can use this runtime library v7.6?

Is a higher version number runtime library compatible with a file compiled for a lower version of runtime library?

Thank you.

Hi, I assume that you are trying to compile an m file using MATLAB Compiler Runtime(MCR) v7.6. You need to use MATLAB r2007a for this m file which uses the corresponding MATLAB compiler runtime. Here's a link with more details - https://www.mathworks.com/matlabcentral/answers/102061-what-is-the-version-of-the-matlab-compiler-runtime-mcr-that-corresponds-to-the-version-of-matlab-c

The answer to your second question is No. a higher version compiler cannot be used for a file compiled for a lower version of runtime compiler. You need to use exactly the same MATLAB Compiler Runtime for it.

Thank you Sayam. This is exactly the answer I was looking for.
