latsq - Latin Square
M = latsq(N) creates a latin square of size N-by-N containing
the numbers 1 to N. N should be a positive integer.
A latin square of size N is a N-by-N matrix filled with N different
numbers in such a way that each number occurs exactly once in each row
and exactly once in each column. They have applications in the design
of experiments. The output M is also known as the (backward shifted)
circulant matrix of the vector 1:N.
Examples:
M = latsq(4) % ->
% 1 2 3 4
% 2 3 4 1
% 3 4 1 2
% 4 1 2 3
% latin square of categories
C = {'goat','cabbage','wolf'}
idx = latsq(numel(C))
M = C(idx)
% Randomized latin square
V = randperm(6)
M = V(latsq(numel(V)))
