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 the aim-mat project. For further information look here: http://www.mrc-cbu.cam.ac.uk/cnbh/aimmanua...SignalClass.htm "signal" is mainly used for generating, modifying and displaying auditory signals on the timescale of 44100 Hz, but it works on all timescales.

nestedSortStruct and nestedSortStruct2 do a nested sort of a one-dimensional struct array by two different methods. That is, the struct array is sorted by one field, then those entries of the array that have the same value for that field are sorted by a second field, etc. If you want to sort by only one field, you can call nestedSortStruct and use a simple string instead of a cell array for fieldNamesCell, or you can simply call sortStruct. The restrictions are that the fields must be single numbers or logicals, or chars (usually simple strings).

The EJS Oscillator Chain model shows a one-dimensional linear array of coupled harmonic oscillators with fixed ends. This model can be used to study the propagation of waves in a continuous medium and the vibrational modes of a crystalline lattice. The Ejs model shown here contains 31 coupled oscillators equally spaced within the interval [0, 2 pi] with fixed ends.

Ejs Oscillator Chain model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive.

2 utilities for solving the basic problems in statics- the one dimensional beam and plain truss. both receive model info as input (has to be built as a MATLAB file, see examples) and produce output results such as reactions values and internal forces in members. See the README file for info..

This program represents a further development of the standard powerful 'nlinfit' facility already in matlab. The major problem with 'nlinfit' is that it can only handle fitting of one dimensional arrays (x, y) where x is the independent variable and y is the dependent one. The program fit2 uses another program 'fitfit' where the user fitting function can be defined. This user defined function is defined in line 6 of fitfit as ff in terms of a,x,y. The input arguments to the program are 1- a which is an array representing the starting values of the free fitting parameters ( similar to that when nlinfit is used) The length of a must be equal to the number of parameters used in the user defined function to be fitted (line 6 in the M-file "fitfit" 2- x and y are each a one dimensional array representing the independent variables 3-...

Often I have to extract a subset of a two-dimensional array for further analysis. Usually I do this with logical indexing. But most often the problem with logical indexing is that I get a column vector which I then have to reshape or index into a new array. cropmat solves this problem. The function crops a subset of an array based on the axis-aligned minimum bounding rectangle. One advantage is that you can perform the operation on several matrices (e.g. coordinate matrices generated by meshgrid) at one time.

MAT2TILES is basically a wrapper for mat2cell but with a more convenient interface when you are simply trying to decompose an N-dimensional array into equal-sized chunks. It takes the desired chunk-size as an input argument, whereas mat2cell does not. MAT2TILES also has some convenient shortcuts for when you only want to tile along particular dimensions (see below). USAGE: C=mat2tiles(X,D1,D2,D3,...,Dn) C=mat2tiles(X,[D1,D2,D3,...,Dn]) will produce a cell array C containing adjacent chunks of the array X, with each chunk of dimensions D1xD2xD3x.

This code performs the stochastic tourist walk dynamics over a one-dimensional disordered system. The code return the density of distinct visited sites on one trajectory.

The 1D Heat Transfer software is used for to study one-dimensional heat transfer (steady and unsteady states). It can be used for the geometries: wall, Lx = width; long cylinder, Lx = length; sphere, Lx = R/3 - with value zero for the flux in the center - and semi-infinite wall, Lx must be greater than the studied position. The software simulates problems with constant and variable properties. The initial condition can depend from the position. Type of boundary conditions: temperature, flux and convection.

The Proptima SimpleCut creates an effective solution for one-dimensional cutting problems. In one-dimensional cutting tasks we want to make pieces of materials with different lengths through cutting up bigger pieces. The raw material can only be procured in some fixed lengths. The goal is to minimize material usage and procurement as well. Proptima products..

1DCutX is the length cutting optimization add-in for Microsoft Excel. It finds how to cut one-dimensional (1D) linear stocks (bars, pipes, beams, wires, etc.) in order to minimize the material waste and the cost without leaving Microsoft Excel. It reads the spreadsheets, performs the optimization and generates the detailed report and the graphical layouts instantly within the same workbook.

Any production or building company or even an individual handyman faces the common-known problem of cutting big linear stocks by smaller pieces.

Cut 1D X is an Automation Component used for obtaining optimal cutting designs of one dimensional pieces which may have angles different of 90 degrees at their extremities. Cut 1D X can be used for cutting linear pieces such as bars, pipes, tubes, steel bars, or any other material used by industrial applications. Cut 1D X can be used within any programming enviroment such as Delphi, C++Builder, Visual Basic, Visual C++ etc

Features:

Pieces to be cut can have angles different of 90 degrees at their extremities.

Real Cut 1D is a computer program used for obtaining optimal cutting designs of one dimensional pieces which may have angles different of 90 degrees at both extremities. Real Cut 1D can be used for cutting linear pieces such as bars, pipes, tubes, steel bars, etc.

Features:

Pieces to be cut can have angles different of 90 degrees at their extremities. A lot of material can be saved by properly matching 2 pieces having sharp extremities. For instance, if you match 2 pieces having 45 degrees at their extremities you will save as much as the height of the pieces.

This class can be used to read and parse Comma Separated Values (CSV) files.It can parse each CSV file line and store the retrieved data in a bi-dimensional array class variable.The separator character and line length limit values are configurable..
