As I can split a vector 4x18 in four workers each with a 1x18 table, selecting the vector for each worker in parallel computing with spmd.

That would sound like something more natural for parfor ?

You could do that using distributed arrays. For example
spmd
d = codistributed(rand(4, 18), codistributor1d(1))
end
will result in each worker storing a 1x18 portion of d.

Thank you so much, it works really good. But if i want to distributed the array in a some especific way in to the workers, for example if i had 4 workers and a array of 5x18 and i want in the first worker an array of 1x18, in the second 1x18, the third 2x18 and in the forth 1x18,how could i do, thank you so much for your answers.
