How to avoid duplicate random value when open multiple matlab session ?

1 visualizzazione (ultimi 30 giorni)
Currently I need to open 10 diffierent matlab session simultaneously using a .bat file. In these 10 sessions, i need to generate random number uniformly distributed on the interval 0.25 to 0.5. From what I observe there were a lot of duplication of my random number from these 10 matlab session. My guess is that because they are open simultaneously using the bat file and my interval is quite short, the random seed somehow does not change much.
I am using the rand function to generate random real number
Please help me with this issue. Thank you !

add this in your code
seed = randi(2020);

this code is just for generating random seed. everytime your code is called, a new seed is called hence generating a different random numbers. add your code of random number after this code
For example
seed = randi(2020);% Genrates random number bw 1 and 2020
rng(seed) % control random numbers from here onwards with rng
% Your code containing random number. it is prefferable if you add these two lines at the start of code
