Hi Theo,

the different Matlab processes communicate via the file system in the multicore package. All function input and output arguments are saved to/read from the file system. In your example, the multicore master process will save 100 files of about 8 MB (1 million doubles) to the disk which are read by the slaves. The overhead is in this case clearly larger than the benefit of the parallel processing.

Hi people,
I a question about the hungarian algorithm. this algorithm is optimal algorithm for the assignment problem, and the time complexity is O(n^3), right?
But , if the input is the multidimensional matrix, it's possible to use the hungarian algorithm? how does it change the algorithm and the time complexity ?
thanks

Scratch my first suggestion on my last post. I just read David's post below and was not aware of the -nodisplay flag.

Excellent function. It was really helpful for me in the case of multi-objective optimization
