random matrix with fix data

 Hi all,

I generated A matrix including random and normal variable as below:

   A=randn(4); 

   Whenever I run this command, different data will be generated. 
   How can I generate A matrix with fixed random variable. 
   I mean in every running A matrix doesn't change.

Thanks,
