Given mean anomaly and eccentricity of an orbit, eccentric anomaly can be calculated using Kepler's Equation. However, the equation is nonlinear, and an iterative technique must be used. This program uses a fixed-point iterative technique to output eccentric anomaly to a user defined tolerance,... Platforms: Matlab

Linear feedback shift registers (LFSR) are a simple method of generating sequences, including pseudorandom number sequences. The LFSR code provided is very unrestricted, allowing for any feedback polynomial, initial state or decimation factor. The code is written for a 32 bit LFSR, but minor... Platforms: Matlab

Simple example of the use of the FMINSEARCH function to fit the blackbody equation to the emission spectrum of an incandescent body for the purpose of estimating its color temperature and emissivity. fitblackbody.m is the fitting function.
