my random changes its values during running my code

i working on my matlab code to generate data size with specific mean and value. so i used the following syntax:

mu=30;var=100;

ts=mu+sqrt(var)*randn(1,10);

but each time i run the code, the number inside ts vector changes and i need it to constant.

this problem affect the remaining steps of code and make size changes.

any solution to this problem??

You can generate random numbers that are repeatable with saving and restoring the generator setting.

rng(1,'twister');

mu=30;var=100;
ts=mu+sqrt(var)*randn(1,10);

ts
