How do I define a laser beam(gaussian) in Matlab with given beam waist and centroid. The task is to then add noise to this laser beam and calculate the change in the centroid using a centroid detecting algorithm.

Guess first you define "beam waist" and "centroid" for those who know something of Matlab but little (if any) of lasers.
Then, what you mean, specifically, by "define in Matlab" -- a function that returns something like a 2D PDF of intensities or the like, maybe?
The crystal orb is dark on this one, sorry...
