E = string.empty () returns a $0\times 0$ empty string array. string.empty (m, n, …) or string.empty (sz) returns an empty string array of the requested size, which must have at least one dimension equal to zero. A lone dimension gives a square size, so string.empty (3) is an error while string.empty (0) is $0\times 0$. As for zeros, a negative dimension counts as zero, and a size vector with nothing in it names no size and gives $0\times 0$.
