I am trying to fit multiple Gaussians in a TEM image. I want to achieve this using coding rather than the curve fitting tool.

Hi Mishra,
here it the function you need fitgmdist.
It does fitting using Gaussian mixture model.

As Adam says, fitgmdist fits multi-dimensional data. In the doc page you see the input is a matrix X where rows are observations and columns are variable. Therefore, if you are dealing with 3-dimensional data, your matrix X will be size N-by-3, where N is the number of observations.
