A variation of Matlab's cart2sph, that transforms a vector of Cartesian coordinates (East, North, Up) to radar coordinates (Range, Azimuth, Elevation). Note the different definition of radar coords vs. spherical coords, which require this different function (see exact definitions within the help comment).
input format #1: [...] = xyz2rae(x,y,z) input format #2: [...] = xyz2rae(xyz) output format #1: [range, azimuth,...
Calculate the dynamic stiffness using spectral element for a beam in space
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...
Boundary Control via Modified Smith Predictors for Beam Equation with Delayed Boundary Measurement
Smith predictor and its variants are applied to the boundary control of Euler-Bernoulli beam equation with delayed boundary measurement....
The program uses a simple algorithm to calculate the deflection at each point of a cantilever beam subjected to arbitrary loading distribution, the program also calculates and plots the bending moment and shear force in the beam.
a design of a beam that could be used as a bridge
Regulation bang bang model of ball on beam.
Basic GUI for Beam Propagation Method for advancing gaussian beam in a profiled medium. It can be used to demonstarate the concept of beam propagation.
Any comment will be welcomed.
The X Beam ("the cross beam") is a cross platform C++ 3D world simulation engine with powerful customization support. It is currently being developed for Linux, Mac OS X, and Windows.
This program simulates Gaussian beam propagation through a Fabry-Perot interferometer with adjustable error angles. The result is the intensity behind the cavity at a screen perpendicular to the propagation direction. It contains a GUI for setting...

This program simulates the interference pattern of two Gaussian beams. The simulation assumes that the beams are combined at a beam combiner which tilt angle (along x-direction) is arbitrary. The distance z from the position of minimal beam waist...
ZEMAX is an optical simulation code (http://www.zemax.com/). One of its features, Physical Optics Propagation, calculates the electric fields as they travel through the simulated optical system. The results can be saved in the ZEMAX Beam File...
BALLBEAM demonsrates Proportional-Derivative (PD) control as applied to a ball and beam simulation experiment. Execute by calling with no arguments.
P and PD controllers are implemented which manipulates the beam angle in response to...
The parallel computing toolbox version 5.0 for MATLAB 2010b includes an initial capability for NVIDIA CUDA use. This entry provides a simple paraxial beam propagation method [BPM] solver that utilizes the added GPU capability. A script is also...
The toolbox implements a simple (Timoshenko) beam with rigid disks. The model computes the eigenvectos (modes) at various speeds of rotation incorporating various effects like gyroscopics, stiffness of bearings. The results are presented...
The function calculates the Global to Local coordinate transformation matrix for a beam in space. [x0,y0,z0] and [x1,y1,z1] are the coordinates of the beam ends. alpha is the twist over the axis perpendicular to the beam cross sectional area,...
A function for carbonation depth measurement out of an image of phenolphthalein sprayed fresh fracture of concrete beam. The algorithm can be easily adopted for similar proposes, like chloride penetration. a description of the algorithm...
This is a simple FFT based beam propagation method for potential-free 1+1+1D Schrodinger equation. The software if flexible and allows to introduce high-order derivatives in the term (very handful if is needed to include dispersion effects). For...
