Details:


Trying to compile and use mtimesx [1] fails with this runtime error: 

error: mtimesx_test_nd: mtimesx.mex: failed to load: mtimesx.mex: undefined
symbol: mxCreateSharedDataCopy


Replacing mxCreateSharedDataCopy(..) by mxDuplicateArray(..) seems to be a
workaround. However, it might cause performance penalty and/or memory leaks.
