I am trying to use the MATLAB Coder app to compile a MATLAB function into C code, but I get the following generic error:
ERROR: "Generation of trial code failed"
When I press the view errors button, nothing is showed.
When I use the "codegen" command for just code generation (without any sort of compiling), I get the following error:
??? CODEGEN requires a MATLAB Coder license.
I have a floating network license. How do I resolve this?

In R2017a and prior, the issue can occur because of the unavailability of a license. However, the MATLAB Coder app is supposed to warn you about the unavailability of the license. This lack of warning is a known bug and has been fixed for R2017b. For now, you can use the following command as a workaround to ascertain that you have the MATLAB Coder license available before proceeding to the Coder app:
>> license('checkout','MATLAB_Coder')
If you observe the generic error in newer releases, use the "codegen" command instead of MATLAB Coder app to get to the bottom of the issue:
codegen - MATLAB Coder
