Many thanks to Oliver Woodford and all the other contributors of this effective strategy. Anyway I would like to submit a potential issue when using Matlab Parallel Computation Toolbox. In particular i'm trying to use this scheme inside a parfor, obtaining a segmentation fault while trying to convert a matlab handle in C++ pointer.
Since this is not a pure Matlab topic, I posted the detailed question on stackoverflow.
