Method Of Least Squares

The program computes the tie lines, the operating and mixing points and the number of equilibrium stages using the Hunter and Nash graphical method of a liquid-liquid extraction problem. One feed of acetic acid (35 wt %) in water which flow rate = 1000 kg/hr is extracted using a solvent... Platforms: Matlab

Both functions caculate the Lomb normalized periodogram (aka Lomb-Scargle, Gauss-Vanicek or Least-Squares spectrum) of a vector x with coordinates in t, which is essentially a generalization of the DFT for unevenly sampled data.The codes are transcriptions from Fortran of the subroutines found in... Platforms: Matlab

variogramfit performs a least squares fit of various theoretical variograms to an experimental, isotropic variogram. The user can choose between various bounded (e.g. spherical) and unbounded (e.g. exponential) models. A nugget variance can be modelled as well, but higher nested models are not... Platforms: Matlab

This is a wrapper function to solve optimization problems (using FMINCON) of the form:min w.r.t. X of CostFunc(X) = beta*(W_ls*F(X)) + (1 - beta)*(max(W_mm*F(X)))subject to: A*X Platforms: Matlab

The zip includes:(1) lsqAffineSpace: a 'low level' routine that takes a set of m-dimensional real sample data and returns the optimal-fit k-dimensional affine subspace, with some options for discarding outliers.(2) lsqPlane and lsqLine: lsqAffineSpace wrappers, that compute optimal line and... Platforms: Matlab

This function implements a method of using genetic algorithms to optimise the form of a polynomial, i.e. reducing the number of terms required in comparison to a least-squares fit using all possible terms, as described in the following paper:Clegg, J. et al, "The use of a genetic algorithm to...

inilib is a C++ library which provides a method of saving the "state" of a program. inilib library provides a means of storing a number of arbitrary settings in memory with an easy access interface, as well providing means for saving the information to and loading it from disk. Data is stored... Platforms: *nix

DBIx::Timeout is a Perl module that provides a safe method of timing out DBI requests. The method described in the DBI documentation uses unsafe signals, which may cause memory corruption. DBIx::Timeout instead uses a separate timeout process. The problem with using POSIX sigaction() is that... Platforms: *nix

Combining the high speed analysis provided by the open source combustion analysis software of catool with the industry leading data aquisition hardware of National Instruments, catoolRT provides a highly powerful yet low cost method of using your existing combustion analysis and data acquisition... Platforms: Windows

Whenever a superclass implements a __init__ method to initialize its attributes, subclasses derived from it have to invoke the __init__ method of the superclass. This script is a different mechanism of initializing the attributes of a superclass with default values, achieved by overriding the... Platforms: Windows, Mac, *nix, Python, BSD Solaris

Function: Savitzky-Golay Smoothing and Differentiation Filter The Savitzky-Golay smoothing/differentiation filter (i.e., the polynomial smoothing/differentiation filter, or the least-squares smoothing/differentiation filters) optimally fit a set of data points to polynomials of different degrees....

It is application of the method of operator A of PDE linked to problem of Rc-network electrical propagation on cable.I will publish results computing online mathworks. Platforms: Matlab

This solver computes the internal loads on each member of two dimensional isostatic truss structures by using the method of joints.Since the Theory of Deformations is not considered in this program, displacements of the structures are not computed. All assumptions of Rational Mechanics are made... Platforms: Matlab

This example solves a complex curve fitting problem that involves parameter pooling and stratification using a nonlinear least-squares approach. This example also takes advantage of some new language features with MATLAB 7. * Anonymous functions * Nested functions Platforms: Matlab

This guide will step you through one method of adding documentation and demos to a user-created toolbox. A simple example toolbox is provided. Platforms: Matlab

Implements a method of adding "Recent..." menus for Applications, Folders and/or Documents (Similar to the Finder's "Recent Items" menu). Items may be added to the recent menus by dragging them on the application, the dock icon or the window of the running application. The project is factored... Platforms: Mac

This package was developed to provide an easy method of including Roman Numeral values in the output of programs written in C/C++. There are example programs that demonstrates the use of the functions included in the library. The utilities `romannum' and `romandate' show possible uses for the... Platforms: Mac
