BOXCOUNT Box-Counting of a D-dimensional array (with D=1,2,3).The Box-counting method is useful to determine fractal properties of a1D segment, a 2D image or a 3D array. If C is a fractal set, with fractal dimension DF < D, then the number N of boxes of size R needed to cover the set scales as... Platforms: Matlab

sql4array can execute SQL SELECT queries on bi-dimensional array, for which the first dimension is the row number and the second dimension the field names.The WHERE clause can be used to specify conditions with operators such as =, >,The results are returned as arrays and can be sorted with the...

Langton's Ant - it's just eye-candy ;-) This program is based on an amazingly simple algorithm - An "ant" is walking across a two-dimensional array of bits, if the bit the ant steps on is 0 (color 2) the ant turns left, if the bit is 1 (color 1) the ant turns right, the bit the ant has just left... Platforms: Windows

The fundamental package needed for scientific computing with Python is called NumPy.  This package contains: - a powerful N-dimensional array object - sophisticated (broadcasting) functions - basic linear algebra functions - basic Fourier transforms - sophisticated random number capabilities...

JVClifford is composed of Java/Java3D packages and executables jars that provide for Clifford element definition, Geometric Algebra operations and geometric scenes modelling and rendering using the n-dimensional geometric algebra affine model Platforms: Windows, Mac, Linux

Open2Dprot is an open-source proteomics project for the development of bioinformatic tools for n-dimensional protein expression data analysis of quantified protein expression across multiple samples from research experiments. Platforms: Windows, Mac, Linux

Given a large one-dimensional array, this script breaks it into blocks of contstant length and compute min and max for each block, the so-called "peaks data". Platforms: Windows, Mac, *nix, Python, BSD Solaris

This program computes the projection of any n-dimensional vector y onto the canonical simplex Dn defined by Dn:={x: x n-dimensional vector, 0 Platforms: Matlab

This is a very simple function to find the local maximum in any dimensional array. As simple as it is it still gives nice results.I use the imdilate() function as a maximum operation and then compare the data to the result.The function receives three parameters:the data, a vector defining the... Platforms: Matlab

A signal object (an object of class "signal") is a set of data in an one dimensional array, combined with information about its sample rate, starting time and other useful infos. A number of methods makes it easy to generate and modify signals."signal" is used and tested for considerable time in... Platforms: Matlab

How to fit a 2D Gaussian function to noisy data in Matlab? Or data with another number of dimensions and arbitrary fit function?It took me a while to find out how Matlab does this by the functions lsqcurvefit, fmincon or fminsearch. This project demonstrates how to use these functions to fit ND... Platforms: Matlab

The Matlab convhulln is a gateway to the quickhull algorithm ( see www.qhull.org ). In my opinion, one weak point of this mex routine is that it processes all the points without performing any preliminary filtering.In many cases it would be faster if only the point that can be part of the...
