c = cell(1,100)
for i = 1:100
c{i} = randi(100)
end
I tried doing this but it only gives 100 arrays of size 1.
I need 1-D arrays
Any other solution is gladly welcomed.
Thank you!

Since all of your arrays are the same size, I would consider stacking them in one of the dimensions in which they have size 1.
A = randi([-10 10], 5, 8);
In this example A contains 5 "arrays" (the rows) of random integer values between -10 and 10, each "array" having size [1 8]. To use the third "array":
third = A(3, :)
For 2-dimensional arrays, you could stack them in the third dimension like pages in a book.
B = randi([-10 10], 3, 3, 7);
fifth = B(:, :, 5)
