I want to run many experiments using parfeval. How can I preallocate an array of the futures? The sample below results in an error saying the constructor needs more arguments.
experiments = parallel.FevalFuture(100)
for i = 1:100
experiments(i) = parfeval(@magic, 1, 5);
end

Loop backwards.
clear experiments
for i = 10:-1:1
experiments(i) = parfeval(@magic, 1, 5);
end
experiments
