Vogel Approximation Method

This is an approximation of the Voigt function within the Humlicek regions 3 and 4. The approximation is one given by S.M. Abrarov et. al. "High-accurace approximation of the complex probability function byFourier expansion of exponential multiplier" (2010).x = sqrt(ln(2))*(nu - nu0)/alphaDy =...

These files provide a fast implementation of the image-source model (ISM) for the simulation of room impulse responses (RIRs) in small-room acoustics. This implementation produces RIRs that are virtually identical to those obtained with the standard ISM, but the simulations are up to two orders...

Fitting a t-copula using the method of moments described in Quantitative Risk Management by McNeil, Frey and Embrechts. The outputs from this function correspond to those of the statistics toolbox's copulafit('t',u) . For large datasets, tcopulafit is immeasurably faster than copulafit('t',u)....

In FDTD method we are truncated the problem space.But in truncating we face the problem of reflection in its boundary.The absorbing boundary condition(ABC)but its quite difficult to make 2D ABC and make use in FDTD method. This problem is solved by PML.Suppose a wave propagating outward,it will...

The HTTP 'POST' method is provided as a mechanism for uploading data as part of a URL request. There are two methods for encoding this data: application/x-www-form-urlencoded, in which each parameter is inserted as part of one long string, and multipart/form-data, in which each parameter gets its...

FDTD is Finite Difference Time Domain method,but due to truncated it it will cause the reflectional on its boundary that will cause unnecessary noise to our simulation domain. So minimizing this unwanted signal we use PML(Perfectly Matched Layer)which can absorb this unwanted signal and so there...

MdoDsller's method uses three points, It constructs a parabola through these three points, and takes the intersection of the x-axis with the parabola to be the next approximation. The order of convergence of MdoDsller's method is approximately 1.84. This method could be advantageous if looking...

This script is capable of solving a convex quadratic programming problem by Wolf's method. For the convergence of the algorithm it is necessary that either Hessian of the objective function be positive definite or positive semidefinite Hessian with linear term zero. For theory of Wolf method and...
