How to generate a "static" weighted random samples using Matlab?

I would like to generate some static weighted random samples using Matlab. I am now using randsample() to achieve weighted random samples, the command is as follows:

P = randsample([1 2 3 4],12,true,[0.15 0.35 0.35 0.15]);

However, P will change every time when I run this command...

Any thoughts on how to make P static? Thanks in advance!
