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...

We can exploit the symmetry of a real, positive definite, symmetric matrix by using the Cholesky decomposition to compute the inverse.The built-in MATLAB inv function uses LU decomposition which requires extra pivots and operations. Rarely does one actually need to compute the inverse of a matrix...
