I observe strange results from using constructs like vectorize(vectorize(M)), where M is a matrix which elements are matrices. Could someone explain the logic? Or is this a bug?   nested-vectorize.sm (19kb) downloaded 18 time(s).Edited by moderator 20 May 2016 21:18:42(UTC)

Mike, Your M matrix is a collection of items. Mathematica defines as 'cell array' Matlab defines MDA [Multi Dimensional Array] The vectorie operator must have at least two arguments to produce. You are attempting to vectorise M over itself, a non sense in some way. Try to multiply M*N, where 'N' will be of similar construct of different values and put that under the vectorise operator. You should get result. Jean
