Code generation to C/C++ compiler option "fp:strict"

When running codegen, the makefiles always have the "fp:strict" compiler option. Is there anyway to modify this option?

As a work-around, I can manually modify the makefile manually and re-run it.

I could not reproduce this in R2019b version of MATLAB (and I have not verified this is the case in the previous releases).

You can take a look at coder.updatebuildinfo function to modify the compiler flags.

You can try doing something like below if that is what you want :

coder.updateBuildInfo('addCompileFlags','/fp:fast');

You can also take a look at post-codegen-command :

Hope this will help you.

So the default *.mk file or build.ninja file in: "C:\Program Files\MATLAB\R2017b\toolbox\coder\coder\mex\c" include this flag and so it works its way into the generated makefile.

For example, Matlab 2017b "mex_msvc.mk" has this on line 18.
