Auto Gaussian & Gabor Surface fit
---
Functions to fit a 1D Gaussian to a curve and a 2D Gaussian or Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit for many different choices of parameters then refining the most promising set of params through least-squares (exhaustive search followed by refinement).
All functions support 2 methods for computing error bars on the parameters: bootstrapping and MCMC.
autoGaussianSurf(xi,yi,zi) fits a 2D Gaussian to a surface, defined as:
zi = a*exp(-((xi-x0).^2/2/sigmax^2 + (yi-y0).^2/2/sigmay^2)) + b
It can also fit a tilted 2d Gaussian or isotropic 2d Gaussian.
autoGaborSurf(xi,yi,zi) fits a Gabor, defined as:
zi = a*exp(-(xip,.^2+yip.^2)/2/sigma^2)*cos(2*pi*xip/lambda + phase) + b
Where:
xip = (xi-x0)*cos(theta) + (yi-i0)*sin(theta);
yip =-(xi-x0)*sin(theta) + (yi-i0)*cos(theta);
The Gabor fit calls autoGaussianSurf internally, using the fact that the absolute value of a Gabor in the Fourier domain is a Gaussian.
autoGaussianCurve(xi,zi) fits a 1D Gaussian to a curve.

Matching pursuit for 1D signals - Performs matching pursuit (MP) on a one-dimensional (temporal) signal y with a custom basis B.
Fast B-spline class - fastBSpline - A fast, lightweight class that implements non-uniform B splines of any order Matlab's spline functions are very general. This generality comes at the price of speed.
Fit GLM with quadratic penalty - Generalized linear models (GLMs) are a natural extension of linear regression models in which eta = X*w is related to y by a fixed nonlinearity and a possibly non-Gaussian noise source.
