I'm developing my own Toolbox called 'Mix Toolbox'.

My folders struct is:

+mix/amp2dbfs.m

function [dbfs] = amp2dbfs(sample)
%AMP2DBFS return the sample amplitude value using dBFS scale
%
%   USAGE: 
%   [dbfs] = amp2dbfs(sample)
coder.inline('never');
    dbfs = 20 * log10(abs(sample));
end

I call this function typing:

out = mix.amp2dbfs(value);

I'm trying to compile this function to MEX. In the MATLAB Coder I got:

-> Generating trial code: OK

-> Building MEX: OK

-> Running test file: ERROR

The invoked code did not call entry-point function: 'amp2dbfs'.

I tested the generated MEX file and it works.

I think that this MATLAB Coder error is only about the call 'amp2dbfs' and not 'mix.amp2dbfs'.

My question is: Is there a way to remove the final error in "Running test file" process?

MATLAB Coder App does not support generating code for an entry-point function that is nested inside a package. I can think of the following workarounds:

use the command-line interface ("codegen") -- cd to +mix folder, call codegen from there
move amp2dbfs to outside of +mix
Create a separate entry point function (e.g. "main.m") that calls mix.amp2dbfs and generate code for that entry-point function.
