The code implemented a special case of the ellipsoid fitting technique proposed in the paper Least Squares Ellipsoid Specific Fitting, corresponding to case k= 4. Just put the two files in the same directory and run "testFit4". You can change the noise level to observe the fitting accuracy and efficiency of the algorithm. It works well when the underlying shape characterized by the data points is quite spherical. However, if this is...
The Spherical Self-Organizing Feature Maps is a contemporary technique for data clustering and visualization.
The main advantages they offer are the following: 1. Smooth training 2. Implementation in arbitrary dimension...
Examples of Three dimensional curves described in Chapter 7 of the book: "CRC Standard Curves and Surfaces" by David von Seggern (1993).
The zip file includes the following curves:
a) Helical curves: -...
MATLAB implementation of IGRF11 fortran code as function for calculating Earth mean magnetic field. Implementation has been modified to default to GPS reference coordinates with output B components North, East, and Vertical. Spherical harmonic...
Discriminant Functions is one of statistical technique used in Pattern Recognition for separating classses. This is parametric methods, means, it requires that mean and covariance of class is known. In other words, Probability Density of...
TDFig is an interactive matlab GUI. It displays a 3D objects in the traditional 4-view window (top, front, right and camera). It also allows users to grasp these objects and move them anywhere in the 3D space.
Just run:
Spherium allows for the creation of a cornicopia of curious 3D objects and offers full interactive control over lighting and orientation.
Spherium contains a function (fig2pic) which can construct very high resolution images of any...
A stack-based sequential priority first decoder that returns Maximum-Likelihood solutions to spherical LAST coded MIMO system-type problems, i.e., a lattice decoder with spherical boundary control. In such problems, the depth of the search tree is...
In 1975, Vincenty published a rapidly converging algorithm for computing the distance between points on an ellipsoidal earth. The algorithm is precise to within a few millimeters. Since then, his algorithm has since seen significant implementation...
ELEV = GETELEVATIONANGLE(GR,H1,H2,REFFECTIVE) Determines the elevation angle of a target based on ground range (GR), altitude of the observer (H1) and the altitude of the target (H2), and the effective radius of the Earth...
The Mogi [1958] model allows to calculate analytic solution for surface deformation due to a point source in an elastic half-space. This model is widely used to simulate ground deformation produced by local perturbation like volcanic magma...
In this paper i try to associate a linear dynamical system dX/dt=AX to the PDE wave equation.So i discretize the space to step h,and set the limited develpment.it is well application also for spherical wave.J.C Willems gives good standing from ODE...
This code takes an expression for a normalized AF in spherical coordinates and creates a 3D plot in cartesian coordinates. Examples are specific to Antenna Theory and Design (2nd Ed) by Stutzman and Thiele.
Anthropomorphic arm with 6 DOF and spherical wrist It calculates the Inverse Kinematic of an Anthropomorphic arm with 6 DOF. 'q' is the solutions in radiant and K is the direct Kinematic matrix.
K = [ n s a p; 0 0 0...
A program to calculate spherical Besselfunctions with minimum effort.
This ZIP file contains function that provide simulation of the following models: - Free space loss calculation - Reflection quantization in generic surfaces for vertical and horizontal polarizations - Plane Earth loss calculations,...
The Rhalotel spherical flash panorama tools is the available software for a real presentation of the whole environment via macromedia flash technology on the internet. It's not an ordinary "photograph scrollator" neither a classic...
