fix random rumbers

Started by Romain Govav March 1, 2005

Dear all,

I am writing a program within which I am genereting
random normal numbers. I would like to get the same
random numbers from run to run. This helps me to check
my program.

Can anybody help me?

thanks in advance
Romain




Use help on randn. The relevant sentence for you is.

RANDN('state',0) resets the generator to its initial state.

Hope this helps,
Nandan

Another thing you might try:
 
I think you can feed the seed you like to rand. So you can choose the same (known) generator for as long as you want. I did this in C but also Matlab should let you. Check the help on how to do it.
