This depends a bit on the programming tools you use. There are
random number generators available in most programming languages.
In C there is a generator, rand(), that draws pseudonumbers
from a uniform distribution. In matlab there is a gaussian
generator, randn(), as well.

Check out the documentation for your programming language.
Looking for a function named "rand" is a good place to start.
If you find a uniform generator, you can use the numbers it
produces and convert them to other types of distributions.

Hi,

Is there some quick ways or software tools to add  kind of noise, for
example gaussian noise etc to each tuple in a vector.

Thanks,
