as an illustration of the above concepts, it is known that both 2 and 3 are typical ranks of formula_31 while the generic rank of formula_32 is 2. practically, this means that a randomly sampled real tensor (from a continuous probability measure on the space of tensors) of size formula_33 will be a rank-1 tensor with probability zero, a rank-2 tensor with positive probability, and rank-3 with positive probability. on the other hand, a randomly sampled complex tensor of the same size will be a rank-1 tensor with probability zero, a rank-2 tensor with probability one, and a rank-3 tensor with probability zero. it is even known that the generic rank-3 real tensor in formula_31 will be of complex rank equal to 2.
