You can control random number generation using 'rng()' function. The usage is rng(seed).
rng(seed) seeds the random number generator using the nonnegative integer seed so that rand, randi, and randn produce a predictable sequence of numbers.
Hope that helps..!!

See rng() if you are using a reasonably recent MATLAB.

Why this doens't work for me?
rng(1,'twister');
x = rand(1,5)
x =
0.4170 0.7203 0.0001 0.3023 0.1468
x = rand(1,5)
x =
0.0923 0.1863 0.3456 0.3968 0.5388

Ran in:
You need to reset the seed.
rng(1,'twister');
x = rand(1,5)
x = 1×5
0.4170 0.7203 0.0001 0.3023 0.1468
rng(1,'twister');
x = rand(1,5)
x = 1×5
0.4170 0.7203 0.0001 0.3023 0.1468
