Ex Catalogue Returns

This module stores generic meta-data about an astronomical catalogue.It takes a hash with an array refernce as an argument.The array should contain a list of Astro::Catalog::Item objects. Alternatively it takes a catalog format and either the name of a catalogue file or a reference to a scalar,... Platforms: *nix, Perl, BSD

ProdLer is a multi-language PHP content management system that allows you to make a products catalogue quickly. The data that will be saved on the DB is: brands of the products, categories of the products (n levels), and dealers for the products. Platforms: Windows, Mac, *nix, PHP, BSD Solaris

This script returns the file size of an HTTP URL. It doesn't work on other types of URLs (e.g. FTP, FILE, or LDAP), just HTTP. Works using just the standard Perl distribution, no extra modules needed. Platforms: CGI and Perl

Qexec establishes database connections, executes queries and returns the results in arrays. Query text literal values can also be escaped. Platforms: Java

This script uses cookies to let a dropdown list remember which option was chosen when a user returns to the page.It comes in very useful if you have a page that is frequently accessed and users tend to repeatedly chose the same option from a list. Platforms: JavaScript

The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with reference to given cluster. Platforms: Matlab

Computes the DFT of N real values and returns the firstN/2+1 DFT coefficients. N is an integral power of two. Platforms: Matlab

If you pass in 2 vectors it returns the unnormalized distance between the vectors, the accumulated distance between them, the length of the warping path (the normalizing factor), the warping path points and both warped input vectors.You can plot the results too if select the pflag=1 Platforms: Matlab

This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw. Platforms: Matlab

Takes the data length, window length and window overlap length as inputs and returns the number of windows that will result. Will also return the start samples and end samples of each window if asked. Platforms: Matlab

This code takes an input of a set of given (x,y) points in the Cartesian coordinates and returns the center and radius of the minimum circle enclosing the points.This code is based on that of Yazan Ahed, and contains no changes in the algorithm but only in the structure.The previous code was... Platforms: Matlab

Rt: returns seriesalpha: VaR levelOUTPUT:CFVAR: Cornish fisher VaR with alpha probability and time horizon as the returns series frequancy Platforms: Matlab

For a symbolic input function f, returns the symbolic Hessian matrix. A real time saver imho I don't know how useful anyone will find this, but eh, my professor made us do it on the test, so I figure this will save at least someone the headache of having to find the Hessian by hand (provided they... Platforms: Matlab

Using the 1976 US standard atmosphere model, this function returns pressure, denisity, temperature, and speed of sound at a given altitude. Works for both English and metric units. Platforms: Matlab

RA=ROUTH(R,EPSILON) returns the symbolic Routh array RA for polynomial. The following special cases are considered:1) If the first element of a row becomes zero OR2) If one encounters a row full of zeros.>>syms ep>>a=routh([1 1 2 2 3 5],ep)The above given case is for encountering a zero in the... Platforms: Matlab

[A,B,C,D]=era(h,n,N,Ts,def);This function returns the state-space model (A,B,C,D) in continuous or discrete time. The input parameters are the discrete-time impulse response function (IRF); the order of the system; the number of samples to assembly the Hankel matrix and the sample... Platforms: Matlab

EvalfisBetter simulates the Fuzzy Inference System for the input data and returns the output data. Its was develop to work with mandani FIS type. Its differ fron evalfis by using the rule weigth to do the exponencial of the consequent part of each rule. Platforms: Matlab

GETHGVBASE returns polymorphism data from the human genome variation db http://hgvbase.cgb.ki.seHGVDATA = gethgvbase(SNPID) reads in a %hgvbase web record fromEMBL and creates a structure DATA %containing fields correspondingto the hgvBase keywords.FIELDNAME DESCRIPTIONS: a complete %description... Platforms: Matlab

This function returns the coordinates for a 2-D spring, with the possibility of adding offsets at the two ends.The spring is automatically sized using the maximum expected length and the number of coils.Use >> help springcoordFor more information on usage.Please let me know if you have any... Platforms: Matlab

Wigner3j(j1,j2,j,m1,m2,m) returns the Wigner 3j-symbol, where j1, j2, j, m1, m2, and m are half-integers. Physically, the Wigner 3j-symbol is closely related to the Clebsch-Gordon coefficient , the square of which is the probability that a system of two particles with angular momentum j1 and j2...
