rand()?

for k=1:3
  rand('seed',k);
  a=rand(1,5)
end

The generated random numbers will be repeatable.

Not sure what you are really asking. There have been a number of different ways of seeding the random number generator(s). This might be a useful starting place: http://blogs.mathworks.com/loren/2008/11/05/new-ways-with-random-numbers-part-i/

well i need to generate different noise like sequence for different values of a function ...

i mean suppose function is [1 2 3 4 5 6 7 8 9]

for 1 i need to generate a PN sequence tha i can generate every time for 1..

and for 2 another and so on ...

thanx for the link let me try it ...thanx again
