This is an instructional GUI to be used for learning how Euler angles, DCMs, quaternions, and Euler vector parameters relate in the rotation of cartesian frames (A to B). Can also be used to convert between all 4 values, however see below for a function that accomplishes this.Features:- All 12... Platforms: Matlab

At last Matlab do it!!!Useful tool to plot a 3D implicit surface defined in cartesian coordinates. You can give f(x,y,z) = 0 as a string or as a function handle. Type for usage. Remember to leave your comments and ratings...Thanks!;) Platforms: Matlab

This entry contains the demo presented as part of two separate MathWorks webinars related to MATLAB-to-C code generation. In this demo, we feature a Kalman filtering algorithm for tracking moving objects and will demonstrate how to automatically generate C code from MATLAB functions.Automatic... Platforms: Matlab

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must... Platforms: Matlab

The program is an ordinary m-filethe matrix g(*,*) can be used to punch in the metric values in terms of symbolic variables x1,x2,x3,x4(co-ordinate axes)The program first computes the Affine connection(Christoffel symbols) stored in Gamma matricesThese are then used to construct and solvegeodesic...

Generally, in finite element models degree-of-freedom of all nodes be equals. But, a Heterosis finite element model has each of the corners are assumed to possess three degree-of-freedom (one displacement two rotation w,Qxx,Qyy) and centroidal node has two degree-of-freedom (two rotation...

This demonstration illustrates the use of a complex space vector to represent a three-phase signal . It also shows the transformation of the 3-phase signal 'ABC' into an equivalent 2-phase system 'alpha_beta'. The only restriction to the 3-phase signal is that the zero-sequence component is zero...

Conversion routines to take a surface (a function z of (x,y) or (theta,r)) and convert this into a solid; much as meshz does, but a little more useful for outputting as an STL for frabrication in a 3D printer. There are two cases, one in Cartesian co-ordinates, and the other in polar... Platforms: Matlab

This function was originally designed as a replacement for the Mapping Toolbox function bufferm, which calculates a buffer zone around a polygon. The original bufferm function had some serious bugs that could result in incorrect buffer results and/or errors, and was also very slow. As of R2006b,... Platforms: Matlab

B = ALLCOMB(A1,A2,A3,...,AN) returns all combinations of the elements in A1, A2, ..., and AN. B is P-by-N matrix is which P is the product of the number of elements of the N inputs.Empty inputs yields an empty matrix B of size 0-by-N. Note that previous versions (1.x) simply ignored empty...

CYL3D(Zin,theta_min,theta_max,Rho,H,meshscale) plots the 3D profile Zin as a mesh plot on a cylindrical surface of radius Rho, with mesh size determined by meshscale, for equally spacedangles between theta_min and theta_max. H is the cylinder height. CYL3D(Zin,...,meshscale,plotspec) plots the 3D... Platforms: Matlab

Plots the contours of a function defined on an unstructured triangular grid directly, without the need to interpolate back onto a Cartesian array.I have attempted to replicate much of the functionality of the regular "contour" function.Type "help tricontour"Type "contourdemo" for some examplesYou...
