Matrix Decomposition Matrix decomposition using, e.g. the Cholesky decomposition requires the correlation matrix to be positive definite. That is, the eigenvalues must all be positive. In finance, this is rarely the case, and one often observes negative eigenvalues, or zero eigenvalues. These two functions do... Platforms: Matlab

Frequency-resolved optical gating (FROG) I started with Adam Wyatt's FROG program (on this website) but added to it and edited it beyond recognition. I did, however, subtract one useful feature: This program, as written, is SHG-FROG and GRENOUILLE only!! (Adam Wyatt's program was more general.)--> The program "prepFROG" takes a raw...

Poiseuille Flow in a Rectangular Channel LU Decomposition is applied to a sparse banded matrix. We show how fill-ins can make solution by elimination not manageable. The same matrix is used to solve the Poiseuille flow problem in a rectangular channel using the finite differences approach. The result obtained using this numerical... Platforms: Matlab
