MATLAB函数的mie散射和吸收 MATLAB Functions for Mie Scattering and Absorption(MATLAB Functions for Mie Scattering and Absorption。A set of Mie functions has been developed in MATLAB to compute the four Mie coefficients an, bn, cn and dn, efficiencies of extinction, scattering, backscattering and absorption, the asymmetry parameter, and the two angular scattering functions S1 and S2.)

Convolutional code performance in AWGN Channel

providing YBus for load flow

This code expains kalmanswarm optimization method.All files have been written on matlab 2007a. This method has been explianed with various benchmark functions. This optimization method can be directly compared with other unconstrained optimization method like GA or pso for effieciency and speed. This method is much faster as compared to genetic algorithim.
