If you require distribution along a different dimension, you can use the
redistribute function. In this example, the argument 1 to codistributor1d
specifies distribution of the array along the first dimension (rows).
P>> distobj = codistributor1d(1);
P>> I = redistribute(I, distobj)
P>> getLocalPart(I)
