Circular Dichroism

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal).The package also includes two examples. One checks the calculation against the... Platforms: Matlab

Program calculates eigenvalues, modal parameters and normalization constants for a thin circular plate with elastic edge supports. Both translational and rotational constraints are considered. User can modify the constraints and vary Poisson ratio. Platforms: Matlab

Analysis and simulation of orbits in the circular-restricted three-body problem (CRTBP), where primary and secondary bodies move in circular orbits about the common center of mass, and effect of gravitational attraction of the smallest body are ignored. The applications described here are for... Platforms: Matlab

% C = CIRCONV(A,B,N) performs the N-point circular convolution% of vectors A and B. C is returned as a row vector. A and B% must be vectors, but may be of different lengths. N must be% a positive, non-zero integer. The results of CIRCONV will% match that of CONV if N>=( length(A) + length(B) -... Platforms: Matlab

Ympyris project is a circular falling blocks game. Ympyris is a falling blocks game that uses a circle instead of a rectangular grid. Ympyris is a game that combines the idea of Tetris to the polar coordinate system. In normal Tetris-clones you move the falling blocks left and right. In... Platforms: *nix

This is a companion to Matlab's Statistics toolbox ksdensity function and Philipp Berens' CircStat toolbox.The difference with Matlab's ksdensity function is that this function is adaped to circular data, such as wind orientation. Using Matlab's function will give biased values at the extremities... Platforms: Matlab

In this version the particles are bouncing in a square or circular bounding box with perfectly elastic collisions.Particles have masses and radius.It's a very educational script to learn something about particle physics.You can set a flag and save the trajectories on a file log. Platforms: Matlab

For an idealized pendulum with massless arm of length L, traveling along a vertical circular track of radius R with constant angular velocity W, this program will integrate the equations of motion given the above parameters and initial conditions, and will then animate the system, tracing the...
