Modelling Gaussian Noise Using PDF or Equation?

[vinsley]

Halooo~~~
I'm new in Matlab software,recently my supervisor given me a task.:X use any function in Image Processing Tools to generate Gaussian Noise,and i have to develop Gaussian Noise by using pdf or its equation with its mean and Standard Variense as parameter and add it to a image.Can somebody help me for that le?
Thank for reading..

The central limit theorem of the random number theory says
that the rather large sum of any random numbers gives the Gaussian random number.
Therefore
Yoy can load any PDF file, add, say 100 neigboring bytes in it and get the
genuine Gauss number.
