Dbm Circular

This program calculates and plots the photonic bands for a 2D photonic crystal consisting of cylinders with circular cross-section and infinite height, arranged in a triangular lattice; we consider in-plane propagation and two independent polarization states: E-pol and H-pol (E-field and H-field...

Arbitrary-order polynomial datum is fit to and extracted from input xy data. Outliers - defined based either on a non-parametric or mutliples-of-standard deviation criteria - are optionally identified and "set aside". The interative solution proceeds until there are no remaining outliers in the...

Given an input primal gear, the toolbox compute its associated dual gear together with the associated distance between the gear centers.The gears are described as a discretized polar curve. The dual gear is solved by a numerical integration of the non-sliding condition. The distance between the...

In this demo, we walk through the steps of animating the 3D motion of a 747 aircraft given a helical trajectory described in parametric form. The challenge is to make the aircraft move such that its axis of symmetry is always pointing along the velocity vector. By reducing the problem to circular...

The code uses array indexing to implement shifting of the matrix. It is about 2.5 times faster than using interp2 with 'nearest neighbor' option for shifting of the matrices. Inspiration for optimized array indexing comes from a snippet on circular shift in: "MATLAB array manipulations tips and...
