Setting seed in random ('normal')
조회 수: 9 (최근 30일)

I am using random('Normal',2,5,T,1) to generate vector of random numbers from normal distribution with mean 2, variance 5. I want to set the seed so that I can get same set of random numbers each time I run the m file. I am using matlab 7.10.0 (R2010a). I have tried with rand('seed',0) command before random('Normal',2,5,T,1) but it does not serve my purpose. Can anyone help me please?

In that version of MATLAB, I am pretty sure that there are separate streams for rand() and randn(). I think random('Normal',...) effectively uses randn() in its guts. So, I believe you will get what you want if you just use
>> randn('seed',0)

I do not know about seed you r talking about,but if you want to get same sat of random numbers every time do this,
rng('default');
random('Normal',2,5,T,1);
rng('default');
random('Normal',2,5,T,1);
Every time you use random('Normal',2,5,T,1),make sure to put rng('default') before it & u end up with same set f random data every time

@ Walter: Is there a way to see which functions are not defined in which versions of Matlab in help file/ in forum ??,like rng is not defined in R2010a

Sorry, Luffy, there is no known list of which functions are defined in which version. If, though, your profile here is attached to a MATLAB license, then when you look at a documentation page, you can ask to search other releases, and hunt around until you find the version that introduces (or drops) the function.
