Examples

Find the rank of magic squares. Access only the local portion of a codistributed array.

r = zeros(1, 40, codistributor());

for n = drange(1:40)

r(n) = rank(magic(n));

end

r = gather(r);

Perform Monte Carlo approximation of pi. Each worker is initialized to a different

random number state.

m = 10000;

for p = drange(1:numlabs)

z = rand(m, 1) + i*rand(m, 1);

c = sum(abs(z) < 1)

end

k = gplus(c)

p = 4*k/(m*numlabs);

Attempt to compute Fibonacci numbers. This will not work, because the loop bodies are

dependent.

f = zeros(1, 50, codistributor());

f(1) = 1;

f(2) = 2;

for n = drange(3:50)

f(n) = f(n - 1) + f(n - 2)

end
