gmsk modulation of numerical data generated by a random source, the output of the modulator give two signals, only for demonstration, the first is gmsk signal and the other is gaussien frequency pulse shape Platforms: Matlab

Flow past a wedge is governed by the Falkner-Skan equation. This equation admits only numerical solution, which requires the application of the shooting technique. The program plots the velocity for various wedge angles. The result obtained is in agreement with figure 8-10 in page 352 of Deen's... Platforms: Matlab

L-BFGS-B is a collection of Fortran 77 routines for solving nonlinear optimization problems with bound constraints on the variables. One of the key features of the nonlinear solver is that the Hessian is not needed. I've designed an interface to the L-BFGS-B solver so that it can be called like... Platforms: Matlab

Ever wonder how the weights and abscissae are calculated for the numerical conversion from radiance to flux? The long and the short of it is that Gauss-Jacobi quadrature determines the weights and abscissae which is similar to Gaussian for low-point quadrature but differs substantially for... Platforms: Matlab

In this code,we are concerned with the numerical minimization of energy functionals in Hilbert Space involving total variation for gray-scale 1-dimensional inpainting problem.Applications are shown by finite element method. Platforms: Matlab

Complex step differentiation (CSD) is a superior numerical differentiation approach. Normally, it is more efficient and accurate than finite difference appraoch. This package provides a way to improve the MATLAB fmincon function using the CSD. Platforms: Matlab

Have you ever wanted to call the engCallMATLAB function, only to realize that it isn't available? Well, now it is! This Fortran routine mimics the functionality of the mexCallMATLAB function, but for engine applications. Has the same argument list as mexCallMATLAB with the addition of the Engine...

The physunits toolbox is an attempt to confer dimensional "awareness" to the MATLAB environment. The motivation for this, as well as a suggested way to go about it, are explained in% Petty, G.W., 2001: Automated computation and consistency checking ofphysical dimensions and units in scientific... Platforms: Matlab

mxLogicalFunctions.for provides a suite of functions to support conversion of Fortran logical variables to/from MATLAB style mxArray variables in mex routines or engine applications. Assumes that the MATLAB logical class uses 1 byte for storage of each logical element. When testing a MATLAB... Platforms: Matlab
