gaussfitn

Fit N-dimensional scattered points with Gaussian+constant

This FEX submission provides gaussfitn, a wrapper function that uses lsqcurvefit to fit the N-dimensional Gaussian (plus constant) model function,

Here A and D are unknown scalars, μ is an unknown Nx1 mean vector, and Σ is an unknown NxN covariance matrix. By imposing lower and upper bounds 0<=D<=0, this can also be used to perform pure Gaussian fitting. The submission also provides a helpful tool, namely gaussFcn, for post-plotting and assessing the fit.

See help documentation for gaussfitn() and gaussFcn() as well as the accompanying Examples.mlx for demonstrations of usage.
