MATLAB: Loadlibrary mfilename put in sub folder

Question

I have a rather large Matlab project (over 100 function files etc.) which I have organised into folders to make it easier to keep track of. The project at its heart has a C DLL which it loads to access some physical hardware. When this is loaded it creates an m file (named through the 'mfilename' option when calling 'loadlibrary'). I would like if possible this m file to be placed in one of the subdirectories not the top level (current) directory.

I tried simply changing the mfilename option to include a relative path but this was completely ignored and the mfile placed in the top directory regardless.

Is there anyway of getting this to happen automatically?

Furthermore, is it possible to get the 'thunk' files to also be placed in a subdirectory to keep things clean?

Along similar lines but less importantly, when compiling mex functions, is it possible to specify the output directory for them?

Answer 1

The thunk file can be placed anywhere by adding the thunkfilename option with a path to the desired location. The only way to control the placement of the prototype file is to issue a cd command to the desired location first. This guarantees that the location is on the matlab path which is required to run the prototype file. Full path names are supported for the header and dll file names so it should be possible to generate these files in any location. An alternate solution is to copy/move the files after generating them.
